Creating your Chicken Avocado Melt Sandwich is straightforward. Follow these steps for delicious results:

1. Prepare the Chicken: Season the chicken breasts with salt and pepper.
2. Heat Olive Oil: In a large skillet, heat the olive oil over medium heat.
3. Cook the Chicken: Add the chicken breasts to the skillet and cook for about 6-7 minutes per side or until fully cooked. Ensure the internal temperature reaches 165°F (75°C).
4. Slice the Chicken: Once cooked, remove the chicken from the skillet and let it rest for a few minutes. Then, slice it thinly.
5. Mash the Avocado: In a bowl, mash the ripe avocado with a fork. Add salt and pepper to taste.
6. Start Building the Sandwich: In the same skillet, place two slices of bread. Spread a layer of mashed avocado on each piece.
7. Add Chicken: Place generous slices of the cooked chicken on top of the avocado.
8. Melt the Cheese: Top each sandwich with two slices of cheese. Cover with the remaining slices of bread.
9. Toast the Sandwich: Cook the sandwiches in the skillet over medium heat until golden brown, about 3-4 minutes per side. Press down slightly with a spatula for even browning.
10. Serve: Once both sides are golden and the cheese is melted, remove from the skillet. Cut in half and add any additional toppings, like sliced tomatoes or lettuce, if desired.

These simple steps will guide you in creating an incredible Chicken Avocado Melt Sandwich that impresses everyone!
