- 1/4 cup mayonnaise
- 1 tablespoon ketchup
- 1 teaspoon Dijon mustard

- In the same skillet, increase the heat to medium-high. Divide the ground beef into two patties and season with salt and pepper. Cook for about 4-5 minutes on each side or until desired doneness is reached.

- Add the remaining tablespoon of butter to the skillet. Grill the sandwiches over medium heat until the bread is golden brown and the cheese is melted, about 3-4 minutes per side.
- Remove from skillet, slice in half, and serve warm.
