Creating the Chicken Avocado Melt Sandwich is straightforward. Follow these easy steps:

1. Prepare Ingredients: Start by shredding the cooked chicken and mashing the avocado in a bowl. Add salt and pepper as necessary for flavor.
2. Combine Chicken and Avocado: In the bowl with the mashed avocado, fold in the shredded chicken until evenly mixed. If desired, add mayonnaise for extra creaminess.
3. Prepare Bread: Lightly butter one side of each bread slice or drizzle with olive oil.
4. Assemble Sandwich: On the unbuttered side of a slice of bread, spread the chicken and avocado mixture. Top with a generous handful of shredded cheese, then place another slice of bread on top, buttered side facing out.
5. Grill the Sandwich: Heat a skillet or griddle over medium heat. Place the assembled sandwich on the skillet. Cook until the bread is golden brown and crispy, about 3-4 minutes.
6. Flip Sandwich: Carefully turn the sandwich over and continue to grill until the other side is golden brown and the cheese is melted, about another 3-4 minutes.
7. Remove from Heat: Once both sides are golden, take the sandwich out of the skillet. Let it cool for a minute before slicing.
8. Garnish and Serve: Optionally, sprinkle fresh herbs on top of the sandwich before cutting it in half for easier handling.
