Best value animal proteins
Eggs, chicken thighs, larger packs of chicken breast, tinned tuna, frozen white fish, turkey mince, cottage cheese, and 0% Greek yogurt are the backbone of cheap high-protein eating.
The best choice depends on how you cook. Chicken thighs are forgiving and cheap. Tuna is effortless. Greek yogurt solves breakfast and snacks. Eggs are useful at almost any meal.
Best value vegetarian proteins
Red lentils, chickpeas, kidney beans, baked beans, tofu, edamame, cottage cheese, Greek yogurt, and eggs give strong value. Lentils are especially useful because they add both protein and fibre.
If you are vegetarian and dieting, combine protein sources. Beans plus yogurt, tofu plus edamame, eggs plus cottage cheese, and lentils plus a side of Greek yogurt all help hit the target.
| Food | Best use | Prep note |
|---|---|---|
| Eggs | Breakfasts, salads, wraps | Boil six at once for snacks |
| Tinned tuna | Jacket potatoes, pasta salad | Choose spring water for lower calories |
| Red lentils | Soups, dhal, bolognese | No soaking needed |
| Greek yogurt | Breakfasts, sauces, snacks | Buy large tubs for better value |
| Tofu | Stir-fries, curries, noodle boxes | Pat dry before cooking |
Where to shop
Aldi and Lidl are hard to beat for basic protein staples. Tesco and Asda can compete when larger packs or loyalty prices are available. Iceland is useful for frozen fish, chicken, prawns, and vegetables.
Do not chase the cheapest item if you will not cook it. The best-value protein is the one that ends up in meals rather than forgotten at the back of the freezer.
