What To Buy First
Start with protein anchors: eggs, Greek yogurt or skyr, chicken, tuna, salmon, lean mince, tofu, cottage cheese, beans, lentils and edamame. Then add cheap carbs such as oats, rice, pasta, potatoes, wraps and wholemeal bread.
Frozen vegetables are a high-value habit because they reduce waste and make batch cooking more reliable.
