Some people never use leftovers. To me, that is anathema!

For example, say you went out to eat somewhere and you had steak or you just stayed home and had steak. Steak is expensive. Don't waste any leftovers. Say you have a few scraps of steak leftover that do not look nice and would not look very appetizing on a plate. What can you do with them?
1. Use for a sandwich.
2. Cut into small pieces and make a beef stew.
3. Make steak burritos.
4. Be like Prax and have a peanut butter and steak sandwich.
