I spend around £280 to £380 a month atm. I am trying to keep it at the lower end. That is 2 adults and 3 gannets. Two of whom have Coeliacs. It includes food, cleaning stuff and toiletries.
Use Lidl/Aldi/Tesco/markets/local fruit and veg shop/Costco/poundshops. Also use Approved Food and Rosspa. I also use the Old Style Board and several other boards on MSE.
I meal plan each week and we have some veggie meals each week. I also use my slow cooker a lot. I also make sure that I don't give too much meat each meal, all you need is a childs/adults fist size portion.
For example
Breakfasts are cereal for the kids (weetabix and GF cereal (usually £2.50 a box but Approved Food had 2 for £1 recently so I stocked up)) DH has homemade Nigella's breakfast bars, I have a shake (£4 or on offer from Wilkos but AF have recently had a good offer on another make so I stocked up)
Lunch is packed lunch for the kids DC1 has homemade bread with cheese/ham/jam/chocolate spread etc. (look out for offers on AF and Rosspa), DC2 has Genius bread sandwich (on perscription) with the same fillings, DC3 prefers rice cakes with the same toppings. I then put things like cherry toms, cucumber, carrots, cellery (cut up and in a little pot). A piece of fruit ( bannans, apples, oranges etc.) Dried fruit (buy the big bags and put in little pots). HM cake or somthing similar. I always check AF to see if they have any lunch box type stuff on offer. DH has leftovers from the night before or HM soup (my greengrocers do big bags of near date f&v for 50p which I buy and make soup from that using HM stock from when I do chicken.) I have 2 slices of toast or some crackers.
Main meals are usually cooked from scratch. For example
2.2kg Chicken in the Slow Cooker (yellow stickered £3) served with roast carrot. butternut squash, sweet potatoes and potatoes.
Chicken curry in the SC servedwith rice and HM flat breads ( I stripped the meat left over from the day before and it made enough for us for that meal and enough to be put in the freezer so we could have it again another day. So 10 portions using LO chicken. I make stock from the bones and juice.
Spaghetti Bolognaise. I use 500g of mince fried off with a couple of chopped onions. Add a couple od grated carrots and a handful of lentils. A couple of cloves of garlic, a tablsp of mixed herbs, a tblesp of tomato puree, 2 cans tomatoes, salt and pepper and a beef stock cube. Serve with with spaghetti. Usually have enough left for a portion or two for the freezer.
Chhilli con Carne in the SC with 500g of mince, a couple of chopped onions, 2 tins kidney beans,2 tins chopped tomatos, a couple cloves of garlic, 1tsp of chilli powder, 1 tsp paprika, 1/2 tsp flaked chillis, 2 tblsp tomato puree, and 200ml of beef stock. Served with rice and sour cream. (usually have enough left for a portion or to to go in the freezer.)
Bacon and veg. risotto. Melt butter in the pan and add any left over, bendy veg ie leeks, onions, bn squash, peas etc. Add bacon (used to use Tesco cooking bacon 99p for 500g and use 250g but they no longer do it. Apparantly Aldi do a a good cooking bacon.) Add a packet of risooto rice and stir until coated, Add more butter if necesary. Put in SC and add 1ltr of veg stock (HM or cube) Put n the SC and cook for an hour or so until the liquid is absorbed. Usually have enough left for a portion for the freezer.
Cauliflower and brocolli with bacon and a cheese sauce. Cook florets of cauli and brocolli for 5mins or so. Fry off the other 250g of bacon. Make a cheese sauce, I use a strong cheese so you don't need as much to get the taste (there is usually some on offer somewhare. Also add a splodge of mustard to enhance the flavour) Put veg in a pyrex bowl with bacon, cover in cheese sauce. Bung a couple of slices of bread in a food processor with a lump of parmesean to make a cheesy topping and sprinkle over the top. Put in a hot oven for for 20 mins.
Omlettes with what ever LO veg or meat there is in the fridge.
Puddings are HM cake or tinned fruit, angel delight etc. What ever is cheap in AF. At the moment I am breaking Easter Egss up and they are haveing that for pud.
Snacks are fruit, popcorn or whatever I have got cheap from AF.
