Preheat the oven to 375 degrees and line a baking sheet with parchment paper.
In a large bowl combine the ground chicken, black beans, diced onion, chili powder, cumin, garlic powder, salt, and egg. Mix with clean hands until the ingredients are evenly distributed.
Divide the mixture into eight equal portions and shape each into a small oval loaf. Place the loaves on the prepared baking sheet.
Bake for 22 to 25 minutes until the internal temperature reaches 165 degrees.
While the meatloaves bake, make the salsa. In a medium bowl gently stir together the diced avocados, cherry tomatoes, red onion, lime juice, cilantro, and salt.
Remove the meatloaves from the oven and let them rest for three minutes. Spoon the avocado salsa over the top before serving.
