Creating Cheese-Stuffed Quesadilla Coffins is straightforward. Follow these simple steps:

1. Prepare the Filling: In a bowl, mix the shredded cheese with cooked chicken (if using), diced bell peppers, garlic powder, and onion powder. Stir until well combined.
2. Shape the Tortillas: Using a sharp knife or a pizza cutter, cut a coffin shape into one of the tortillas. You can also use a template for precision.
3. Heat the Pan: Preheat a skillet over medium heat and lightly coat with cooking spray or olive oil.
4. Layer the Tortillas: Place the whole tortilla in the skillet. Evenly distribute half of the cheese mixture over the tortilla.
5. Add the Coffin Top: Place the coffin-shaped tortilla on top of the cheese. Press down gently to help the filling stick.
6. Cook the Quesadilla: Cook for approximately 3-4 minutes or until the bottom is golden brown.
7. Flip Carefully: Using a spatula, carefully flip the quesadilla and cook the other side for another 3-4 minutes until golden and the cheese is melted.
8. Remove and Slice: Remove the quesadilla from the skillet and let it cool for a minute. Use a sharp knife to cut it into portions.
9. Repeat: Repeat the process for additional quesadillas as needed.
10. Serve: Serve warm with salsa or sour cream on the side, if desired.

By following these easy-to-follow steps, you can create an incredible dish that fascinates the guests and delights their taste buds.
