Made haji curry by browning and boiling down horrible offcuts and spices, then sifting out the bones and grisly bits.
$1.50 per serve, $2 with rice and raita. You won't do better for red meat.

Recommend preassure cooker, and if you cooked decent meat and the grisly mess in two seperate pots you could then just add the grisly one as a gravy to double the volume of the good one.
