First I'd put it in the fridge in a bowl and scrape off all the fat. Then I'd heat it, add some water so it looks like soup stock. Taste it. Add veggies, bits of meat, etc. and you have soup. If you don't have enough for a meal, add some bullion, better than bullion, or stock until you do, then add the meat/veggies.
Don't add the veggies, etc. but take a little out of the pot, put it into a bowl, make a flour paste and then add that back into the liquid, you have made gravy.
For me, it depends on what else I've got to eat up which way I go.
IHTH!
