You can disguise cheap cuts of meat - make stir-fry with lots of veggies and asian flavouring, turn sausages into meat-balls which can be fried, roasted or boiled up in an onion sauce, and kidney stew is pretty tasty too.
Liver is good for you and usually very cheap and so is Black pudding.
And Cornish Pasties are yummy and with potato, swede, onion, a little bit of meat and home-made pastry, they don't cost very much.
Our supermarkets offer 'shaved' ham or silverside, very thinly sliced. $2 worth gives sufficient meat to satisfy the family, with salads or put into a quiche or served up in gravy or soup.
You become quite inventive after awhile!
Been there, done that, not so bad now but not yet out of the woods.
