Making the Chicken Avocado Melt Sandwich is an effortless process. Follow these steps for a deliciously satisfying result:

1. Prepare the Avocado: Cut the avocado in half, remove the pit, and scoop the flesh into a bowl. Mash it with a fork until creamy. Season with salt, pepper, and garlic powder if desired.

2. Mix Chicken: In another bowl, combine the shredded chicken with mayonnaise (if using). Stir until well combined.

3. Assemble the Sandwich: On one slice of bread, spread a generous layer of the mashed avocado. Then, layer the chicken mixture on top of the avocado.

4. Add Cheese: Top the chicken with shredded cheddar and mozzarella cheese to create that melty goodness.

5. Top It Off: Place the second slice of bread on top to form a complete sandwich.

6. Toast the Sandwich: In a skillet, heat olive oil over medium heat. Once hot, place the sandwich in the skillet. Toast for 3-4 minutes until golden brown.

7. Flip and Cook: Flip the sandwich gently, and toast the other side for another 3-4 minutes or until the cheese is melted and the bread is crispy.

8. Serve: Remove from the skillet and let cool for a minute. Cut in half, garnish with fresh herbs if desired, and serve warm.
