Butter each piece of bread with a thin layer of butter before placing the bread butter-side down. Then add GRATED cheese to the non-buttered side of the bread.

I used a metal ramekin (you could use glass too) and put the mozzarella cheese inside. Then fill a sauce pan with a small amount of water and put the ramekin in the water (not enough water to make the ramekin float). Heat the water carefully (don't leave it unattended) until the cheese melts. Try to stir the cheese while heating, but be careful not to let the steam or metal burn you. I used a chop stick.
