(by Shirley McNevich)
cheese slice singles (American, mozzarella--whatever you like best)
sliced bread (any style you like)
sliced tomatoes (optional)
sliced cooked bacon (optional)
Place a skillet over LOW heat--spray it with Pam. Butter two slices of bread.
Place two slices of cheese between the bread (unbuttered side) so that the
buttered side of the bread is on the OUTSIDE of the sandwich. Use a spatula
to place the sandwich in the skillet. Cook until bottom side is browned, then
flip and cook the other side. Optional--place tomato and cooked bacon
BETWEEN the two cheese slices before cooking.
