Choose a labelled protein-focused product if protein from the cake itself matters: Sainsbury’s lists 0.6g protein per plain rice cake, while M&S describes its Barbecue High Protein Rice Cakes as high-protein and Tesco lists Kallo Protein Lentil Cakes as a protein source. For a school-holiday lunch, treat any of these as one component rather than the whole meal; check the current pack’s protein per serving, salt and allergen information, and include other foods appropriate to the lunch.
Rice cakes can provide a base for other foods, but a plain cake is not the whole lunch. Bedfordshire, Luton and Milton Keynes Integrated Care Board’s packed-lunch guidance suggests including a protein food alongside starchy food, fruit and vegetables.
Tesco describes Kallo Protein Lentil Cakes as vegan and a protein source. M&S makes its Barbecue High Protein Rice Cakes with pea protein and lentil flour. Compare the current packs’ ingredients and protein per serving before choosing between them.
Read the ingredients and any precautionary allergen wording on the exact pack, then check the school’s rules if the food will go into a school lunchbox. Retailer product information and recipes can change.
Start with the role the cake will play in lunch: a protein-focused snack, or a plain base served with a separate protein food. Then compare labels using the portion that will actually be eaten.
| Priority | What to check | Your needs |
|---|---|---|
| Protein | Read protein per cake or serving on the current pack. Sainsbury’s lists 0.6g per plain rice cake; Tesco describes Kallo Protein Lentil Cakes as a protein source, while M&S describes its Barbecue Rice Cakes as high-protein. | If I am buying the cake for its protein, I want to compare the stated serving sizes—not assume that every rice cake makes the same contribution. |
| Lunch composition | Decide whether the cake is a base or a snack, then consider the other foods in the lunch. Bedfordshire, Luton and Milton Keynes Integrated Care Board’s guidance suggests starchy food, a protein food, fruit and vegetables in a packed lunch. | A portable cake works for us, but I still need to decide what else to pack with it. |
| Salt and portion | Compare salt for the portion being packed, not just per 100g. Snack a Jacks lists 0.63g salt per 23g Salt & Vinegar pack; check the weight and nutrition panel of the pack you buy. | For a flavoured snack, I want to know what one pack contributes to lunch. |
| Ingredients and allergens | Read the current ingredients, allergen declaration and any ‘may contain’ wording. The Food Standards Agency explains that precautionary wording can indicate unintended allergen presence; Tesco warns that product information may change. | If a child has an allergy, I need to assess the exact product and toppings, as well as any school-specific restrictions. |
Sainsbury’s lists 0.6g protein per plain rice cake. A product name or front-of-pack claim does not tell you how much protein is in the portion you plan to serve.
Compare protein per serving on the current pack. If you choose plain cakes as a base, plan a separate protein food for the lunch.
Portable packs differ in size and seasoning. Snack a Jacks lists 0.63g salt for a 23g Salt & Vinegar pack.
Check the salt figure against the weight of the individual pack going into the lunchbox.
Ingredients and allergen advice may change. For a child with an allergy, the difference between an ingredient declaration and precautionary ‘may contain’ wording also matters.
Read the physical pack before serving, including any precautionary statement, and check school rules where relevant.
Kallo Protein Lentil Cakes are a lentil-and-buckwheat, cake-style alternative to conventional rice cakes.
M&S describes its Barbecue High Protein Rice Cakes as a rice-cake-format option made with wholegrain rice, buckwheat, pea protein and lentil flour.
Its plain 135g Rice Cakes offer a base for a lunch that includes a separate protein food.
Salt & Vinegar rice-cake multipacks offer individually packed flavoured snacks for carrying.
Tesco lists own-label rice cakes alongside branded cake-style and flavoured options.
These options include a protein-focused lentil cake and three different snack-bar or flapjack formats. The bars and flapjack are alternatives for a lunchbox, not rice cakes; check their ingredients and any school rules before packing them.

A peanut snack bar, not a rice cake. Check its full allergen statement and any school rules about nuts before putting it in a lunchbox.
No image available
A flapjack-format snack rather than a rice cake. Compare protein, salt and sugar for one 50g bar, and read the current allergen statement.
No image available
A nut-bar option, not a rice cake. Check its ingredients and allergen statement, particularly if nuts are restricted where the lunch will be eaten.
Do not assume that they are. Sainsbury’s lists 0.6g protein per plain rice cake; if protein is the reason for buying, compare the current pack’s amount per serving or serve the cakes with a separate protein food.
Compare protein for the portion you intend to serve, as well as ingredients and allergens. M&S describes its Barbecue Rice Cakes as high-protein, while Tesco lists Kallo Protein Lentil Cakes as a protein source; the latter are lentil-and-buckwheat cakes rather than conventional rice cakes.
Plan the rest of the lunch as well. Bedfordshire, Luton and Milton Keynes Integrated Care Board’s packed-lunch guidance suggests including starchy food, a protein food, fruit and vegetables; a cake or snack is only one part of that selection.
Read the exact pack’s ingredients, allergen declaration and any precautionary wording such as ‘may contain’, then check any school-specific rules. The Food Standards Agency explains that precautionary wording can signal possible unintended allergen presence, and retailer information may change when recipes do.
No: check the pack weight and its nutrition panel together. For example, Snack a Jacks lists 0.63g salt per 23g Salt & Vinegar pack; do not apply that figure to a different pack size without reading its own label.
