For an office packed lunch, choose a maize-based grab bag when you want one larger pack: Tesco lists a 36g Wotsits Cheese bag and a 40g Monster Munch Pickled Onion bag, but labels the Wotsits bag as 1–2 servings and the Monster Munch bag as one. If you prepare several lunches or want a smaller, defined portion, consider individual multipack packets instead; check the exact flavour’s ingredients and allergens before buying.
Who these options suit
Lunch packers looking specifically for maize
Check the ingredient list rather than the shape of the snack. Tesco lists corn or maize in its Wotsits Cheese and Monster Munch Pickled Onion grab bags; Walkers UK lists potato starch first for Quavers Cheese.
Shoppers choosing a defined portion
A grab bag and an inner multipack packet are not necessarily equivalent portions. Tesco labels the 36g Wotsits grab bag as 1–2 servings and the 40g Monster Munch Pickled Onion grab bag as one serving; its Monster Munch variety multipack contains individual 20g packets.
Anyone checking allergens before an office lunch
Read the declaration on the exact flavour and pack, particularly if the snack might be shared. Tesco lists milk for Wotsits Cheese and milk and soya for Monster Munch Pickled Onion; allergens can differ between flavours in a variety multipack.
What to check before choosing
Start with the ingredient list to confirm the snack fits a maize-based choice, then compare the pack size, stated servings and allergen declaration for the lunch you are packing.
| Priority |
What to check |
Your needs |
| Main ingredient |
Look for maize or corn in the ingredients, not just a puffed texture. Tesco lists it for the Wotsits Cheese and Monster Munch Pickled Onion grab bags; Walkers UK lists potato starch first for Quavers Cheese. |
I’m looking for a maize snack, so a similar-looking snack made mainly from another starch would not meet that requirement. |
| Pack and servings |
Compare net weight with the label’s serving count. Tesco marks the 36g Wotsits grab bag as 1–2 servings, the 40g Monster Munch Pickled Onion grab bag as one, and the Monster Munch variety multipack’s 20g inner packets as one serving each. |
For one lunch, do I want a larger grab bag? When packing several lunches, smaller individual packets may be easier to set aside. |
| Label figures |
Check whether calories and salt are stated per serving or per full pack. Tesco lists 197 kcal and 0.62g salt for the full 40g Monster Munch Pickled Onion grab bag; its 36g Wotsits listing gives 148 kcal and 0.47g salt per 30g serving. |
I want to understand the amount in the pack I’m taking, rather than compare figures based on different serving sizes as if they covered the same quantity. |
| Allergens |
Read the contains and precautionary statements on the exact packet. Tesco lists milk for Wotsits Cheese, milk and soya for Monster Munch Pickled Onion, and milk, soya and wheat in the Monster Munch variety multipack’s pack-level allergen information. |
If I’m buying for myself or sharing at work, the particular flavour and packet matter more than the brand name alone. |
Common buying mistakes
-
Assuming every puffed snack is maize-based
A similar texture does not establish the main ingredient: Walkers UK lists potato starch first for Quavers Cheese, while Tesco lists corn or maize for the Wotsits Cheese and Monster Munch Pickled Onion grab bags.
If maize is essential to your choice, read the first ingredients on the exact packet.
-
Using “baked” as a substitute for reading the label
Tesco describes the 40g Monster Munch Pickled Onion bag as a baked corn snack and lists 197 kcal, 10g fat and 0.62g salt for the full bag. The cooking description does not replace those pack figures.
Compare figures on the same basis—per pack, per serving or per 100g—and note how much of the bag you plan to pack.
-
Assuming a grab bag means one serving
Tesco labels the 36g Wotsits Cheese grab bag as 1–2 servings, but the 40g Monster Munch Pickled Onion grab bag as one. Their nutrition panels therefore need to be read alongside the stated serving size.
Check both the net weight and serving count. If you want a smaller packet set aside for each lunch, consider an individually packed multipack option.
-
Relying on a brand name for allergen information
Declarations differ by product and flavour. Tesco lists milk and soya for Monster Munch Pickled Onion, while its Monster Munch variety multipack includes flavours with wheat-containing ingredients.
Read the current packet’s ingredients and allergen statement before packing or sharing it.
Relevant brand references
Wotsits
A cheese-flavoured corn-puff option when a maize-based grab bag is the aim.
- Tesco lists corn (maize) in the 36g Wotsits Cheese grab bag and describes it as suitable for vegetarians.
- Tesco labels that grab bag as 1–2 servings and lists milk in its ingredients. Check its label if you need to distinguish a full bag from a serving.
Monster Munch
The Pickled Onion range offers a maize-based 40g grab bag; a variety multipack offers smaller inner packets.
- Tesco lists the 40g Pickled Onion grab bag as one serving and its variety multipack as 12 individual 20g packets.
- The Pickled Onion grab bag contains milk and soya. Check each variety-pack flavour separately, as ingredients differ.
Quavers
A comparison point for puffed snacks, but not a substitute when maize is a required ingredient.
- Walkers UK lists potato starch first for Quavers Cheese, followed elsewhere in the ingredient list by rice flour and soya flour.
- Its declared allergens include barley, milk, soya and wheat; check the exact packet before buying.

Questions about maize snacks
Are all puffed snacks sold alongside maize snacks made from maize?
No. Tesco lists corn or maize for its Wotsits Cheese and Monster Munch Pickled Onion grab bags, whereas Walkers UK lists potato starch first for Quavers Cheese. Check the ingredients if maize is a requirement.
Are Wotsits Cheese and Monster Munch Pickled Onion free from milk?
No. The product information from Tesco and Walkers UK lists milk for Wotsits Cheese, while Tesco lists milk and soya for Monster Munch Pickled Onion. Read the current label for the exact flavour and pack, especially when choosing a variety multipack.
Does one grab bag equal one serving?
Not always. Tesco labels its 40g Monster Munch Pickled Onion grab bag as one serving but its 36g Wotsits Cheese grab bag as 1–2 servings. Check the serving count alongside the nutrition figures; a smaller inner multipack packet may offer a more clearly defined single serving.
How can I compare salt figures on snack labels?
Check whether each figure refers to a serving, a whole bag or 100g before comparing products. Tesco lists 0.62g salt for the full 40g Monster Munch Pickled Onion grab bag, but 0.47g for a 30g serving of the 36g Wotsits Cheese grab bag. UK Government guidance gives 6g per day as the recommended maximum for adults; the pack figure shows how much the snack contributes.
