What to do with: leftovers you don't want
If it isn't delicious, I don't eat it, but . . . what do you do when you make, say, a large pan of lasagna and it only turns out so-so? I don't really want to keep eating something that turned out sub-par, but I also don't want to throw away almost 6 servings of food.
What do you do when food you make doesn't turn out?
