Place the lime juice in a bowl. Peel and pit the avocado. Cut the flesh into small cubes, place in the bowl, and toss and coat with lime juice. Remove the skin from the chicken legs and discard. Removed the meat from the legs and cut or pull into small pieces. Add the chicken and cheese to the avocado and toss to combine.
Preheat the oven to 375 degrees F. Line a large baking sheet with parchment paper. Set the tortilla chips on the baking sheet in a single layer. Divide and top each chip with some of the chicken mixture. Bake the tortilla chips 6 to 8 minutes, or until nice and hot and the cheese is melted. Arrange chips on a serving platter. Top each one with a small spoon of salsa and a small sprig of cilantro. Serve immediately.
Note: Cooked chicken legs are available in our deli department.
