A grilled cheese sandwich is a classic comfort food that can be made in minutes. Butter one side of two slices of bread and place them butter-side down on a hot skillet or griddle. Layer slices of your favorite cheese between the bread slices and cook until the cheese is melted and the bread is golden brown. Flip the sandwich and cook the other side until golden brown as well. Serve with a side of tomato soup for a delicious and nostalgic meal.
