In another small bowl, combine avocado, juice from half the lime, and a pinch of salt.
In one more bowl, combine tomatoes, onion, cilantro, juice from the other lime half, ¼ teaspoon salt and black pepper, to taste.
To assemble: Layer each with 1/3 cup chicken, 1 tbsp black beans, and sprinkle with 2 1/2 tbsp cheese. Broil for 2-3 minutes or until the cheese is melted. Top each with a dollop of avocado and a spoonful of the tomato salsa, jalapeno black olives. Top each with a small sprinkle of salt.
*I seasoned 1 8 oz breast with 1/8 teaspoon salt and pepper and threw it on the grill pan for 8 to 10 minutes on each side over medium heat.
