I made this for my dad for lunch and he said that there were so many flavors but they all melded well.
Three-Cheese Grilled Cheese Sandwich
2 slices Sourdough Bread
2 slices Swiss Cheese
2 slices Muenster Cheese
2 slices Provolone Cheese
Spread butter on the outside of the bread. Stack the cheeses on the inside. Cook on the stovetop until a light brown perfection.
