for an extra 25p /day you can spend an extra 1.75GPB a week.

so then you can buy these from asda and add it to whatever you want.... why wait for the OP to do the work?

Really depends on location. Cheap canned meats are available. Chickens are cheap but take work (see standard objections to gardening). Roadkill is viable (norm in rural areas). Hunting takes work but can be cheap per pound (somewhere around license around $20, gun for $100, $0.25 per shot).

I just grilled & ate a hamburger. Under $1 for meat, sesame bun, and salsa (easy mix of vegetables).
