The budget pyramid
Build your diet around the cheapest plant foods first:
- Tier 1 — Foundations (cheapest): dried lentils, dried beans, oats, rice, pasta, potatoes, bread, seasonal vegetables, frozen vegetables, canned tomatoes, canned chickpeas.
- Tier 2 — Flavour builders: dried spices, soy sauce, tomato purée, garlic, onions, olive oil, peanut butter. These are cheap per meal.
- Tier 3 — Extras when budget allows: tofu, plant-based meat alternatives, vegan cheese, nuts and seeds, fresh herbs.
💡 The magic of lentils
Red lentils are arguably the perfect food: 25p per serving, 9g protein per 100g cooked, no soaking required, ready in 20 minutes, and they absorb whatever spices you cook them with. A pot of dal costs less than 50p to make and feeds a family.
Seven cheap weekly staples
- Dried red lentils — dal, soup, bolognese, patties
- Rolled oats — porridge, overnight oats, granola, crumble toppings
- Canned chickpeas — curry, roasted, hummus, salads
- Canned tomatoes — pasta sauce, curry, chilli, soup
- Frozen peas — add to any dish, incredibly cheap per serve
- Frozen spinach — nutrient-dense, cheap, lasts forever
- Bananas — the cheapest fruit, great for quick energy and smoothies

Shopping strategies
- Buy dried legumes over canned where possible — 500g dried chickpeas (≈£1.20) = 3× cans of chickpeas (≈£2.40). A slow cooker makes this effortless.
- Use frozen vegetables — often more nutritious than fresh (frozen at peak ripeness) and far cheaper.
- Shop in season — seasonal vegetables cost a fraction of out-of-season produce and taste significantly better.
- Avoid ready meals and convenience products — vegan ready meals are marked up heavily. A homemade meal costs 4–10× less.
- Use discount supermarkets (Aldi, Lidl, budget brands) — their own-label canned goods and dried foods are identical quality at lower prices.
- Bulk buy spices from Asian or African grocery stores — the same spices sold in supermarket jars cost 5–10× less.
What not to spend money on
- Expensive meat alternatives on a budget — Beyond Meat, Impossible, etc. are expensive. Use them occasionally. Tempeh and tofu are far cheaper.
- Specialty "superfood" powders — unnecessary for most people. Whole foods provide the same nutrients at a fraction of the cost.
- Organic everything — prioritise organic for the "dirty dozen" high- pesticide produce if budget allows; go conventional for everything else.
📊 The savings add up
Multiple studies show that vegan diets cost 30–40% less than omnivore diets of equivalent nutritional quality. The savings come from replacing expensive meat, fish, and dairy with cheap whole plant foods.
