Creating the Chicken Avocado Melt Sandwich is straightforward. Follow these simple steps to bring this delicious meal to your table:

1. Prepare Chicken: If using leftover chicken, shred or dice it into bite-sized pieces. Season with salt and pepper.
2. Prepare Avocado: Mash the avocado with a fork if you prefer a spreadable texture or slice it if you want chunks.
3. Toast Bread: Heat olive oil or butter in a skillet over medium heat. While it heats, spread mayonnaise on one side of each slice of bread for added flavor.
4. Assemble Sandwich: On the non-mayo side, layer the shredded chicken, avocado, and sprinkle cheese evenly on two slices of bread.
5. Add Toppings: If desired, add optional toppings like sliced tomatoes or spinach.
6. Top It Off: Place the remaining slices of bread on top of the assembled sandwiches.
7. Grill Sandwiches: Carefully place the sandwiches in the preheated skillet. Cook for 3-4 minutes until the bread is golden brown and cheese starts melting.
8. Flip and Cook: Gently flip the sandwiches and cook for another 3-4 minutes on the other side.
9. Check Cheese Melt: Ensure the cheese is melted and the bread is toasted to your liking. Adjust the heat if necessary to avoid burning.
10. Slice and Serve: Remove from the skillet, let them cool slightly, and then slice in half before serving.
