Follow these easy steps to create your BBQ Chicken Grilled Cheese:

1. Prepare the Chicken: In a medium bowl, mix the shredded cooked chicken with barbecue sauce until well coated.
2. Heat the Skillet: Place a skillet over medium heat. Add 1 tablespoon of butter and let it melt.
3. Assemble the Sandwich: Take two slices of bread. On one slice, add a generous portion of the BBQ chicken mixture, followed by a layer of mozzarella and cheddar cheese.
4. Top the Sandwich: Place a second slice of bread on top to complete the sandwich.
5. Cook the Sandwich: Carefully place the sandwich in the heated skillet. Cook for about 3-4 minutes on one side, until golden brown.
6. Flip and Cook: Add another tablespoon of butter to the skillet. Flip the sandwich and cook for an additional 3-4 minutes, ensuring the other side is equally golden and the cheese is melted.
7. Repeat: Repeat steps 2 to 6 for the remaining sandwiches, adding more butter as necessary.
8. Serve: Once all sandwiches are cooked, cut them in half diagonally and serve warm.

With these straightforward instructions, you’ll have your BBQ Chicken Grilled Cheese ready for all to enjoy!
