Here's a menu plan and shopping list for you all.
Go to asda (I'd go to aldi but I'd need to spend about £5 on the bus; I can walk to Asda). And you don't seem to get lentils in aldi according to mysupermarket.
Buy:
4kg carrots (2 x £1.18 = £2.36)
2 swedes (2 x 79p = £1.58)
4kg onions (£1.67)
2 bags of apples (2 x 90p = £1.80)
2 bags kids bananas (2 x £1 = £2)
3 loafs of the cheapest bread (3 x 45p = £1.35)
2kg red lentils (£3.50)
Packet stock cubes (40p)
3kg porridge oats (3 x 75p = £2.25)
12 pints milk (2 x £1.48 = £2.96)
100g garam masala (60p)
500g margarine (£1)
1kg sugar (88p)
240 tea bags (£3.00)
Total: £25.35
With this you can feast on the following (but good luck carrying it home from Asda first):
Breakfasts: porridge (cooked in water; you can add a bit of milk and sugar at the end if you must).
Lunch and dinner: lentil soup. For a special treat you can chuck in some garam masala and call it dhal. Serve with cheap bread and marg.
Snacks: 1 apple or banana daily (kids only).
Drinks: milk, water or tea (you can have some milk and sugar in it if you want)
So you get 5 a day. Well, the kids do. You get 4. It's just the same 5 a day every bloody day. Forever.
If you want to save some money, you can cut back on extravagances like sugar, garam masala, bread, marg, stock cubes and even tea. Plain porridge cooked in water followed by lentil soup twice a day washed down with tap water for the rest of your life. At least the kids get a piece of fruit a day to look forward to.
You can save money the next week, as you can make shit loads of lentil soup with those ingredients.
