I currently feed 4 of us on under £50 a month. I do a big online shop every few months and get all my tins, dried stuff and cleaning stuff/toiletries-this usually comes in at approx £100. Then I buy the fresh stuff every week, spending between £5 and £40 a week.
Veg is carrots, onions, potatoes, broccoli plus a few others (usually what's reduced/on offer)
Fruit apples, pears, bananas, sometimes clementines. Grapes etc only when on offer.
Cereal own brand weetabix, ready oats, value oats, sometimes own brand shreddies or cheerios
Lunch is leftovers, sandwiches or soup/eggs/beans on toast.
Our meals this week:
Pasta, peas, sweetcorn and pesto (got reduced filled tortellini but would normaly just use normal dried pasta)
Roast pork, roast potatoes, roast parsnips, carrots, broccoli and peas with gravy
Chicken pie (reduced to £1)and left over veg from roast.
Jollof rice with leftover pork
Veg and lentil lasagne
Stir fry (1 chicken breast, lots of veg and noodles)
Cottage pie & veg
Then will make soup with any veg left in fridge, maybe chicken stock from freezer, maybe tinned tomatoes, lentils etc.
