Gooey cheese? Check. Toasty bread? Check. Creamy Tomato soup? Check.
Heat a pan over medium-low heat and place 2 slices of bread on the pan.
Add 2 slices of bread. Add a thin layer of cheese, beans, and 2 tomato rounds to each slice. Sprinkle another layer of cheese, and cover with the remaining 2 slices.
Press down firmly with a spatula. Heat until the bread is golden brown and the cheese is lightly melted, then flip over and toast the other side.
