1. prepare the buffalo chicken mixture: in a medium bowl, combine the diced or shredded cooked chicken with the buffalo sauce and ranch dressing. stir well until the chicken is evenly coated. this is your flavorful filling.

2. combine the cheeses: in a separate small bowl, mix the shredded cheddar cheese and shredded mozzarella cheese. this blend ensures a good melt and balanced flavor.

3. assemble the first layer: lay out two slices of bread. spread a thin layer of the softened butter on one side of each slice. this buttered side will be facing down in the pan to get golden and crispy.

4. fill the sandwich: on the unbuttered side of one bread slice, spoon half of the buffalo chicken mixture. top the chicken with half of the mixed shredded cheeses. place the second slice of bread on top, buttered side up. repeat for the second sandwich.

5. cook to golden perfection: heat a large non-stick skillet or griddle over medium heat. carefully place the assembled sandwiches into the hot pan. cook for 4-6 minutes per side, or until the bread is golden brown and crispy, and the cheese is melted and bubbly. you’ll know it’s ready when you see the cheese oozing slightly from the sides.

6. serve immediately: once cooked, remove the sandwiches from the skillet. for easier eating, you can slice them in half diagonally. serve hot and enjoy the cheesy, spicy goodness!
