A huge pot of soup based on aldi super 6. This week broccoli and celery are on so broccoli soup - maybe with a sprinkling of crispy bacon bits ( small pack of the cheapest bacon slowly fried and crumbled) so onions 69p, broccoli 2x39p bit of a celery from a 69p packand a couple of spuds to thicken , stock cubes from the cupboard and a loaf of nice aldi bread 99p plus some of a approx £1 pack of bacon - max £4 for at least 8 poptions.
Celery soup - 69p celery, some of the onions and a spud plus indulgent 69p cream (but you'd only need half a pot max) and more bread - that's another 4 portions for around £2.
Pasta and pesto is cheap, or home made sauces as above ( ir us you are working from my list chop the left over bacon, fry with onions / celery / any other veg leftovers - fresh ir frozen, herbs and a couple of tins tomatoes. That's almost free except the toms as its all remainders from the rest.
Heck youd be able to splash out of a bit of cheese to top it too.
Puddings- what ever fruit is on offer - aldi usually have something at around £1/ bag and value yoghurts are good.
So that's 3 soup days and 1-2 pasta days ( if you have time/ energy maybe make the pasta into a pasta bake - 500g pasta plus a generous amount sauce will make a huge bake - much better than serving it straight somehow) and you are done for main meals.
Breakfast got to be porridge , absolutely the cheapest thing . I actually like it best with water but as ive spent less than £20 on main meals you can have milk for it and even golden syrup.
If you don't fancy soup the. The same super 6 veg cooked with onions , a tin of toms, curry paste and lots of red lentils will make a yummy dhal - a bag of lentils and a bag of value rice go a long way ( add a tin of kidney beans or chick peas for excitement!).
I think part of the budget secret is my secret to surviving as a home cooking working mum- there is nothing wrong with having the same meal several days running or alternate days. I make 2 big pots of something on a Sunday and thry, with maybe a bean / egg based meal will see 5 of us through the week ( and are very amenable to teenagers who aren't home For family meal times )
