2 slices of bread
Ham / cheese / pineapple whatever you want on it
Put a lil bit of butter on the outside of the bread slices, not too thick.
Put ham / cheese / pineapple or the stuff you want on it in between.
Gently lay down the slice of bread with the butter on the outside in a hot pan, keep it on medium cooking temperature. When one side has a gold color flip the bread slice to the other side, when it has a gold color too it’s done.
