I had another thought while I was cleaning the bathroom.
Another thing that you could base a few meals around is a packet of cooking bacon, some potatoes, some eggs and a bag of frozen cauliflower.
meal one -
cauliflower and bacon soup
cut 1/3 of the bacon into little pieces and cook it in a little oil in a big pan. Add a couple of chopped onions (probably 4 of the value ones because they are small). Cook until soft. Add about 500gms of potatoes, chopped into quite small bits, 1/2 a bag of frozen cauliflower and about 3pints of ham stock (if you made the pea soup up above, you should have stock cubes left.) Simmer until everything is tender and flavours are blended, probably about 20 minutes. Serve with bread.
If the kids are still hungry value rice pudding (15 a tin) and value tinned peaches (about 30p a tin) make a good pudding.
leftovers can be kept in the fridge for lunch the next day.
potato and bacon bake -
thinly slice about 2lbs of potatoes and finely chop 4 onions. Take another 1/3 of the bacon (1/2 of what's left) and cut it into small pieces. layer the potatoes, onions and bacon in a baking dish, finishing with a layer of potatoes. Make 1pint of white sauce and pour over the top. Bake at 160 for about 2hrs. it's nice with carrots and peas.
leftovers can be kept in the fridge for lunch later on.
bacon frittata -
boil about 3/4lb of potatoes and then thinly slice. Chop the rest of the bacon into little bits and fry in a little oil with a couple of chopped onions. Add the potatoes and a handful of frozen peas. beat 6 eggs in a jug with some salt, pepper and a little splash of milk. Pour the eggs over the veg and bacon and cook gently until set. Stick under the grill for a few minutes to brown the top. If you have them serve with sliced tomatoes and cucumber.
Leftovers can be eaten cold the next day with bread and butter.
Cauliflower cheese and chips
Use the rest of the cauli to make cauliflower cheese. if the kids won't eat cheese sauce, just use white sauce again. Serve with wedges made with the rest of the potatoes and some more frozen peas and cooked carrots.
shopping list
1pack cooking bacon 81p
1pk frozen cauliflower £1
2.5kg potatoes £1.18
15 eggs £1.35
1pk frozen peas £1
6pts milk £1.48 (do healthy start vouchers pay for milk?)
1.5kgs carrots 89p
ham stock cubes £1.50 (aldi have them for 49p)
180gms mature cheddar £1.50
kingsmill 50/50 loaf £1
2 tins rice pudding 30p
1tin peaches 35p
So that's 4 dinners and probably 3 lunches for about £13. The eggs and cheese can be used for lunches and breakfasts as well. How about cheesy scrambled eggs on toast or mashed egg in a cup with bread and butter for lunch. You could get another 2 meals for you and the 2 littlest out of the 9 remaining eggs, I would think.
Other cheap but nutritious lunches are
peanut butter and banana sandwiches
peanut butter and apple sandwiches
tuna pasta salad - using a tin of value tuna, a tin of sweetcorn and whatever veg you happen to have - carrots cut into tiny pieces, shredded cabbage, little pieces of cucumber thawed frozen peas - cold, cooked pasta and a squirt of value salad cream.
beans on toast with a little grated cheese.
Cheap breakfasts -
porridge made with half milk/half water and a handful of raisins
toast and peanut butter with a glass of milk and a small piece of fruit
boiled egg and toast
It's bean a very long time since I cooked for very small children, so I can't really remember how much they actually eat. Most of the above feed 4 adults. I would think that you would probably eat about 2 1/2 adult portions between the 4 of you? So there should be leftovers from most of the dinners.
