For a ready-to-eat snack with more protein per 100g than the ordinary lightly salted rice cakes compared here, consider Kallo Protein Packed Lentil Cakes or M&S Barbecue High Protein Rice Cakes. Kallo’s lentil cakes list 26.0g protein and 1.9g fat per 100g; the barbecue rice cakes list 24.8g protein and 16.2g fat per 100g. Compare the amount you would actually eat, check allergens on the pack and confirm local availability before making a trip for either product.
Kallo’s lentil cakes and M&S’s barbecue rice cakes list 26.0g and 24.8g protein per 100g respectively. That is more than the 8.7–9.6g per 100g listed for the ordinary lightly salted Tesco, Asda and M&S rice cakes compared here. Those figures come from the brands’ and retailers’ product information; check the serving you intend to eat as well as the per-100g line.
Kallo and M&S label these protein-formulated products vegan and gluten-free. Those labels do not replace an ingredients and allergen check: Kallo says its Protein Packed Lentil Cakes may contain sesame seed and soya.
If flavour matters alongside protein, compare the rest of the nutrition panel. Kallo lists 1.9g fat and 0g salt per 100g for its lentil cakes, while M&S lists 16.2g fat and 0.60g salt per 100g for its barbecue rice cakes.
Choose between a ready-to-eat protein-formulated cake and an ordinary rice cake with a topping, then compare the pack information for the portion you plan to have.
Consider when: You want a ready-to-eat lentil-and-buckwheat cake; Kallo lists 26.0g protein per 100g.
Bear in mind: It is not a conventional plain rice cake, and Kallo says it may contain sesame seed and soya.
Consider when: You want a barbecue-flavoured option and can check stock at an M&S Foodhall.
Bear in mind: M&S lists 16.2g fat and 0.60g salt per 100g, compared with Kallo’s 1.9g fat and 0g salt per 100g.
Consider when: You already have a suitable topping and prefer to assemble the snack yourself; the British Dietetic Association gives rice cakes with hummus or soft cheese as an example.
Bear in mind: The protein in the finished snack depends on the topping and portion, so it is not a like-for-like ready-to-eat alternative.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per portion | Compare protein per 100g on the same basis, then check the amount per cake or serving. Tesco lists 1.8g protein per Kallo lentil cake. | I want to know what the amount I am likely to eat provides, not just what the per-100g figure says. |
| Fat and salt | Read both lines on the nutrition panel. Kallo lists 1.9g fat and 0g salt per 100g; M&S lists 16.2g fat and 0.60g salt per 100g for its barbecue cakes. | Barbecue flavour appeals to me, but I also want to compare the fat and salt figures before choosing. |
| Pack information | Check the current pack for protein, serving size and other nutrition values. Traffic-light labels show information about fat, saturates, sugars and salt where provided. | I need a quick way to compare packs without relying on the product name. In a 2024 Northern Ireland survey of 611 people, the Food Standards Agency and Ipsos found that 49% actively used traffic-light labelling when shopping for food; this is not a measure of rice-cake purchases. |
| Ingredients and allergens | Read the ingredients and any precautionary allergen statement on the physical pack. Kallo says its lentil cakes may contain sesame seed and soya. | A vegan or gluten-free label does not answer every allergen question I may have. |
| Local availability | Check the selected store before travelling for a particular product. Confirm the shelf label and pack details when you get there. | For a quick top-up shop, I need an option I can obtain locally rather than one that only appears in an online listing. |
Tesco, Asda and M&S list 8.7–9.6g protein per 100g for the ordinary lightly salted cakes compared here, against 24.8–26.0g per 100g for the M&S barbecue and Kallo lentil cakes.
Compare protein per 100g first, then look for a per-cake or serving figure that reflects your intended portion.
M&S lists 16.2g fat and 0.60g salt per 100g for its barbecue rice cakes; Kallo lists 1.9g fat and 0g salt per 100g for its lentil cakes.
Read the full nutrition panel and decide whether the flavour and those figures fit what you want from this snack.
A vegan or gluten-free label does not address every allergen. Kallo says its Protein Packed Lentil Cakes may contain sesame seed and soya.
If an allergen matters to you, read the current pack’s ingredients and precautionary statement rather than relying on a retailer filter.
A top-up shop can depend on what is available at the store you can visit; M&S asks shoppers to select a local store to check its product listing.
Check local stock before making a trip for one product, and confirm the pack information when buying.

A lentil-cake listing for a ready-to-eat top-up snack. Its displayed nutrition differs from Kallo’s current UK product information, and the listing describes the product as vegan while also naming milk in its allergen declaration. Check the physical pack’s protein figure, ingredients and allergen statement before buying; do not assume the listing has the same formulation as Kallo’s current official product.
Not in the products compared here.
