I know that many peole already know how to make a grilled cheese sandwich but not everyone does.  It is actully quite simple though.  

You will need 2 pieces of bread, a non stick frying pan, 2 slices of American Cheese or what ever cheese you are using.  and some butter or margarine.  It is best to take the butter or margarine out of the fridge about 30 minutes before you make your sandwich so that it is easy to spread.  

When you are ready to prepare your sandwich simple spread one side of one of the pieces of bread with the butter or margarine, be generous with the butter or margarine and make sure you get it all over the bread.  Place that piece of bread butter side down in your non stick cooking pan.  Then place your cheese on top of that piece of bread.  Make sure cheese covers the entire surface of the bread, breaking up the second cheese slice and using it to fill in empty spaces.  Place the remainder in the middle of the bread.  

Then butter one side of the other slice of bread and place it with the unbuttered side of the bread on the cheese.  Turn your heat on underneath your pan to about medium heat maybe just a tad higher.  Allow your sandwich to cook checking it after about a minute to see if it is getting golden brown on the bottom.  If not wait a bitl longer and check it again in about 30 seconds to one minute.  Once that side is golden brown take your spatula and carefully flip the sandwhich over then cook that side for about a minute to 2 minutes or until it is golden brown.  Once it is remove it from the pan.  Give it a moment to cool of a bit and enjoy.
