like do I throw my left over olive garden noodles in a deep frier?
Nah, not even close. It's the best way to reheat leftover spaghetti. What you want to do is mix any sauce in with the spaghetti good so it doesn't stick when it's in the fridge. Don't put too much sauce though, just enough to coat the spaghetti. Then when you are ready get a frying pan, put it on medium and put just a little over enough olive oil to cover the bottom of the pan. Throw the spaghetti in there, if you have meatballs slice them in half do the same. Stir here and there until it's hot and put some fresh parm on top if you got it. Enjoy. It's great. Old school Italian way to do leftovers.
