A comforting combo: creamy tomato soup paired with golden, buttery grilled cheese. Perfect for dipping, this classic pairing delivers warmth and nostalgia in every bite.
Heat the soup and water in a 1-quart saucepan over medium heat until the mixture is hot and bubbling, stirring occasionally.
Spread the butter on the bread slices.
Place 4 bread slices, butter-side down, into a 12-inch skillet. Top with the cheese slices and remaining bread slices, butter-side up. Cook over medium heat until the sandwiches are lightly browned on both sides and the cheese is melted.
