I know you are thinking veggie but you can buy a cpl of gammon shanks to braise, an onion, bay leaf, carrot, leek. Cover with cold water and simmer gently for a few hours.
Meal one: gammon, mash, carrots and the braising liquor
Meal two: chopped up gammon spread over suet (atora, flour, water), wrap in foil and steam about 90 mins and serve with parsley sauce and a veggie.
Gammon chopped for carbonara. My version is gammon, parsley, cheese, ladle of liquor and creme fraich.
Any gammon left can go in a pie. Puff pastry roll. Bit of onion, butter, chicken thighs (2), spoon flour, gammon, liquor or stock, cheese, add some cooked leeks.
The two bones will make a hood minestrone with and onion, carrots, shredded cabbage, cpl tins toms. Lunch for two to three days with cruaty rolls.
So that's probably £6-7 on meat and lots of yummy meals.
