How to reheat it: Set the oven at 190⁰, till the cheese stars melting and it gets a crispy crust. If you have only 2-3 slices put them in a pan and cover it with foil. Keep it on the gas stove till the cheese starts melting and it gets a crispy crust.
How to reheat them: If they are without sauce, you can boil them once more for 30-45 seconds. If they are with sauce that contains oil, it would be very difficult to reheat them, because when you reheat them the cheese and oil separate and the food may become very oily. Put the spaghetti in a pan with some oil (it would be perfect if you still have the oil you have used for their preparation) and reheat them. If the sauce contains tomatoes you can also reheat them on the gas stove. Add some water if it is too thick.
How to reheat it: Cut the steak into thin slices and add some oil in a pan. Reheat it till the crust becomes brown.
How to reheat them: Chips are very difficult to reheat because they usually change their taste and texture. In order to obtain the best results you can heat some oil in a pan, then add the chips and keep them till they get crispy. Put them on a napkin and sprinkle salt.
You can see that it not necessary to throw away the food because you can always find some solutions that with some imagination can make your food tasteful again. For instance if you have some fish you can cut it into small pieces and put it in the salad. Hamburgers can be also added in the chili soup.
