For each sandwich, you need:
2 slices of bread
1 ounce of cheese
2 teaspoons soft butter
For a Margherita Use: tomato slices, fresh basil, mozzarella cheese, minced garlic
For Apples 'n' Chedd Use: sliced apples, sharp cheddar cheese
Butter one slice of bread with 1 teaspoon butter and lay, butter side down, in a skillet.
Slice the cheese thinly and lay half the cheese on the bread in the skillet.
Top that with the other filling ingredients.
Top the filling with the rest of the cheese slices.
Butter the second piece of bread and lay it on top, butter side up. (For the Margherita, spread the minced garlic on top of the butter)
Turn the heat to medium and cook for about 2-3 minutes, or until the cheese has softened and the bread is toasted.
Carefully turn the sandwich and cook another 1-2 minutes.
Let cool slightly before cutting in half.
