another kind of melted cheese

Sometimes when you are cooking you are cooking the sort of thing where you have all kinds of food in the same pan or pot, and you are planning on putting it on a bread product, such as a tortilla or some pita bread. But it is too liquidy! Sometimes you have time to keep cooking it until it reduces down, but sometimes you want to eat it sooner. Try this simple trick:

-Cut up or grate some cheese into the pot with all the other food
-Stir it up so it melts. The melted cheese will act as a natural thickening agent.
-Put it on the bread product.
-[optional]- You can still put some grated or cut-up cheese on top and melt it, even if there was already melted cheese in the inside (may I be so bold as to recommend "cheddar" or "cut-up string cheese"?)
