Follow these simple steps to create your Chicken Avocado Melt Sandwich:

1. Prepare the Bread: Start by toasting the slices of whole grain bread until golden brown. This adds a nice crunch to your sandwich.
2. Cook the Chicken: If you haven’t already, cook and shred the chicken breast. You can use leftover chicken or rotisserie chicken for convenience.
3. Mash the Avocado: In a small bowl, mash the ripe avocado with a fork. Season it with salt and pepper to taste.
4. Assemble the Sandwich: Spread a generous layer of mashed avocado on one slice of toasted bread.
5. Add Chicken: Top the avocado with the shredded chicken, spreading it evenly.
6. Add Cheese: Sprinkle the shredded cheese on top of the chicken for that melty goodness.
7. Complete the Sandwich: Place the second slice of toasted bread on top to complete the sandwich.
8. Heat the Pan: In a skillet, heat the olive oil or butter over medium heat.
9. Grill the Sandwich: Carefully place the sandwich in the skillet. Cook for 3-5 minutes on one side until golden brown, then flip and repeat on the other side.
10. Melt the Cheese: Press down gently on the sandwich with a spatula to help melt the cheese and ensure everything warms through.
11. Slice and Serve: Once both sides are golden and the cheese is melted, remove the sandwich from the skillet. Slice it in half and serve warm.
