For one small savoury snack beside your lunch, the individually bagged Snack a Jacks 5x19g multipacks fit the brief. Kallo Dark Chocolate Minis offer four separately packed sweet portions and state a gluten-free recipe, while Sainsbury’s 4x30g yogurt-coated packs suit someone who wants a larger sweet portion. Compare the portion you would actually pack, then check the current label for ingredients and allergens.
Who these packs suit
Lunch packers who want one sealed portion
If you want to put a snack straight into your work bag, look for individual bags inside the multipack. Tesco Groceries lists Snack a Jacks Salt & Vinegar as 5x19g; Kallo lists four Dark Chocolate Minis snack packs; and Sainsbury’s lists its yogurt-coated rice cakes as 4x30g.
People choosing between sweet coatings
Kallo’s dark-chocolate minis and Sainsbury’s yogurt-coated packs offer different portion sizes and label values. Compare the energy, sugars and saturates for the pack you intend to eat, rather than treating both as the same snack because they are rice cakes.
Shoppers checking dietary and allergen information
Kallo describes its Dark Chocolate Minis as a gluten-free recipe, but Sainsbury’s listing also notes a possible milk cross-contamination risk. A gluten-free description does not answer a separate milk or soya allergen question; read the wording on the exact current pack.
What to check before choosing
Start with the pack format and the portion you would take to work. Then compare the label values and ingredients for that portion, especially if you are choosing between savoury and coated snacks.

What to check |
Your needs |
| Individual packing |
Check that the multipack contains separately packed portions, not one larger bag. Tesco Groceries lists Salt & Vinegar Snack a Jacks as 5x19g; Kallo lists four snack packs. |
I want to take one sealed snack to work without opening the rest of the multipack. |
| Portion and nutrition |
Compare values per bag or pack first, noting its weight. For a comparison independent of portion size, look at the per-100g values on the labels too. |
I want to know what is in the portion I will eat. In the Food Standards Agency and Ipsos Northern Ireland’s 2024 survey of 611 people, conducted from 16 September to 23 November, 49% said they actively used traffic-light labelling when shopping for food; that figure is not specific to office lunches. |
| Sweet or savoury |
Check the flavour and coating as well as the pack size. Kallo lists 102 kcal per Dark Chocolate Minis portion pack; Sainsbury’s lists 142 kcal, 9.3g sugars and 4.5g saturates per 30g yogurt-coated pack. |
A small savoury bag may fit the snack I have in mind, or I may prefer a separately packed coated portion. I would compare the actual portions rather than assume the labels describe equivalent servings. |
| Ingredients and allergens |
Read the current pack’s ingredients, highlighted allergens and any precautionary wording for the exact variant. Sainsbury’s lists cows’ milk and soya in its yogurt-coated packs; its Kallo listing notes a possible milk cross-contamination risk. |
If an ingredient or allergen matters to me, I need the information for the pack I am buying—not an assumption based on rice being the main ingredient. |
Common buying mistakes
-
Assuming the rice base settles allergen questions
Coatings and manufacturing warnings matter too. Sainsbury’s yogurt-coated packs list cows’ milk and soya, while its listing for Kallo Dark Chocolate Minis notes a possible milk cross-contamination risk.
Check ingredients and precautionary allergen wording on the current pack of the exact flavour and size.
-
Comparing different packs as though they were one serving
A 19g savoury bag and a 30g coated pack are different-sized portions. Tesco Groceries lists 80 kcal per 19g Salt & Vinegar Snack a Jacks bag; Sainsbury’s lists 142 kcal per 30g yogurt-coated pack.
Compare per-pack values for what you will eat, then use per-100g values if you want to compare the products on the same weight basis.
-
Taking “mini” to mean individually wrapped
Mini describes the rice cakes, not necessarily the way they are packed. A larger bag of minis does not provide several unopened portions for separate lunches.
Look for an explicit pack format such as “four snack packs”, “5x19g” or “4x30g” when separate portions are the reason for buying.
Relevant brand references
These examples describe specific product lines and pack formats, not every rice cake sold under each brand.
Snack a Jacks
A savoury rice-and-corn option where a small, separately packed bag is the main requirement.
- Tesco Groceries lists Salt & Vinegar in five 19g bags at 80 kcal per bag; Sainsbury’s Groceries lists Sour Cream & Chive in the same pack format at 78 kcal per bag.
- These are flavoured products. Check the ingredients and allergens for the variant you choose rather than assuming all Snack a Jacks packs are alike.
Kallo
Belgian Dark Chocolate Minis are a coated alternative sold as four snack packs.
- Kallo describes this product as a gluten-free recipe suitable for vegetarians and lists 102 calories per portion pack.
- Sainsbury’s listing notes a possible milk cross-contamination risk. Check the current pack’s full allergen information before choosing it for a dietary requirement.
Sainsbury’s
Its own-brand Mini Yogurt Coated Rice Cakes provide a larger, sweet individual portion in a 4x30g pack.
- Sainsbury’s lists 142 kcal, 9.3g sugars and 4.5g saturates per 30g pack.
- The product’s label marks sugars and saturates as high per pack; its ingredients include cows’ milk and soya.
M&S
M&S lists several rice-cake styles, including flavoured minis, rather than one uniform grab-bag format.
- Its rice-cake range includes mini, coated and savoury options to compare by pack format.
- M&S states that its dark-chocolate mini rice cakes are not suitable for people with a milk allergy. Check the label of the particular product and pack you select.

Questions about rice-cake grab bags
Can a rice-cake grab bag be the whole office lunch?
The packs discussed here are sold as snack portions, so choose one as a component alongside the rest of your packed lunch rather than treating the grab bag itself as the meal. Tesco Groceries lists the Salt & Vinegar Snack a Jacks bag at 19g, while Sainsbury’s lists its yogurt-coated serving at 30g.
Should I compare values per bag or per 100g?
Start with the bag or pack you expect to eat at work. Use the per-100g figures when you want to compare products independently of their different portion sizes; Kallo lists 102 kcal per Dark Chocolate Minis portion pack, while Sainsbury’s lists 142 kcal per 30g yogurt-coated pack.
Does “gluten-free recipe” rule out milk or soya concerns?
No. Kallo describes its Dark Chocolate Minis as a gluten-free recipe, but Sainsbury’s listing notes a possible milk cross-contamination risk. Check the current pack’s ingredients and allergen statements for each separate requirement; the Food Standards Agency explains that precautionary wording such as “may contain” signals possible unintended allergen presence.
Is an online ingredient listing enough to choose a pack?
Check the current physical pack before relying on its ingredients or allergen information. M&S advises shoppers to read product labels because product information can change, a particularly relevant check when choosing a coated rice cake.
