Not like they are really needed but, take two thick slices of bread, a tablespoon of softened butter and the filling combo. Spread butter on one side of both slices of bread, lay the bread on a work surface, butter-side down, and put the fillings inside.
Place sandwich in an already hot nonstick pan (or several, if you are making more sandwiches) on medium heat.
Cook 5 minutes, flip, then cook 2 more minutes. Cut sandwich in half and eat.
