Besides eating them.
Nobody really likes to serve (or eat) the same thing day after day.
So what can you do? Well, on Monday night I roasted fingerling potatoes as a side dish. On Tuesday night, I mashed them and added one chopped green onion.
On Tuesday night I made meatloaf. Aunt Kate would insist that we should have meatloaf sandwiches today.
Tonight I'm making rigatoni and gravy. This time the gravy will be laced with Italian sausage.
I will mix the leftovers with some mozzarella and assorted other cheeses and freeze for a future meal.
Sometimes I actually plan the leftovers into the original meal. Nifty, eh?
That's what I'm cooking; how about you?
