you need to keep overall costs down as well as food - so no putting the oven on for hours and hours etc. SHop yellow sticker, sign up to Olio and to good to go. Consider using a foodbank, some of the more locally based ones don't need a referral etc but also some places run a cheap bag of groceries - I know here £5 for bag with milk, eggs, veg and enough for 3 meals of something - so tinned stuff, sometimes frozen,
Try and have a cook day each week when you put together several meals and either freeze or fridge them to use later
so Mince get 20% fat and skim it off - can be extended with veg and lentils but on a cook day you can do
a burger with some chopped onion and a bit of egg
bolognese
chilli
savoury mince - to eat with veg and potatoes and or as shep pie etc
I would also make a marinara sauce on the same day - can be used in bolognaise but also saved as just a tomatoe sauce for pasta or pizza etc can add tuna/cheese for proteins with standard spagetti or other pasta.
Roast chicken - look out for in yellow stickers. Roast it for a roast dinner then strip it down - chicken breast two portions, two drumsticks, two wings and then picked meat for noodles. You can use the carcass to make a stock.
- Stock noodles and veg is a good hot lunch soup
- stir fry
- Roast chicken dinner at least 4 portions if wanted
- couple of lunches with drummer and wing sets or pick the meat for sandwiches or salad for green veg
- stock use as a soup base for any soup, I only use onion and carrot as we dont like celery at all in our house
As others have said cook all 4 baked potatoes at the same time - then just microwave or pop in the oven if on to heat through
Snacks
Get some popping corn - the bag of corn makes ALOT of popcorn and it doesn't take very long to pop it for evening snacks and some can be kept in a resealable bag for lunches.
Roasted chick peas flavoured with hers or spices
Humous is easily made to a more simple recipe as is salsa to go with some toasted tortilla. Great as a snack or part of lunch.
So tortilla wraps for lunches, with peppers and onions and maybe some chicken for fajita, use some chilli for another variety. 8 snall ones are not too expensive and last ages longer than bread.
Peanut butter can be a good protein rich snack or part of lunch with fruit or carrots
Cheese sauce is a good basic if you learn to make yourself so goes with pasta, cauliflower, fish etc - basic roux mix for sauce then add cheese and a dash of mustard. Frozen fish is the cheapest.
eggs are amazing and can be used for all sorts.
I like to keep a soup mix in the cupboard as well - mostly pearl barley and lentils, but means you can make a hearty soup out of chunky veg and root veg is coming up to cheap season
keep an eye as to who has the best veg offers as there is quite a bit of competition between supermarkets for this
On another note take the opportunity to have a sort through your belongings in rotation and sell off things you dont want of need - plenty of people will be shopping for gifts and ebay now free to list I understand.
Can you rent a room out under the room scheme ie non taxed income from a spare room, for a while? Can you advertise to friends and rellies as a baby sitter for the mad office party season? Can you do other types of work like cleaning/gardening/organising etc
