Butter, for the pan
4 slices bread (any type you prefer: whole-wheat sandwich, French baguette...)
4 packaged slices Cheddar cheese
1. Butter a skillet and heat it over medium heat.
2. Sandwich 2 slices of cheese between 2 slices of bread and place in the hot skillet. Cook for 2 minutes on each side, or until the bread is browned and the cheese is melted. Repeat with the remaining bread and cheese.
3. Cut each sandwich into 12 pieces and serve with the tomato soup.
NOTE: For crunchier croutons, place the sandwich cubes on a baking sheet and bake them for 5 minutes in a 400°F oven.
