Step 1: Preheat the oven to 400°F. Heat a large non-stick skillet over medium heat and add the ground chicken and onion. Cook until the chicken is no longer pink and the onion has softened, about 10 minutes.
Step 2 - Drain, then add back to the skillet and pour in the broth. Then, add the chili powder, cumin, oregano, onion powder, garlic powder, 1 tsp. salt, pepper, and paprika. Stir to combine. Stir in the black beans and salsa, and corn here if using. Stir and cook until heated through, about 5 minutes.
Step 3 - Cut the avocados in half lengthwise and remove the pit. Scoop out the flesh. Transfer the flesh to a small bowl and add the lime juice and 1 tsp. of salt and mash with a fork until chunky-smooth.
Step 4 - Add the desired amount of chicken mixture into the bowl with the mashed avocado. There will be extra chicken mixture in the pan. We always eat the leftovers in taco shells or a bowl like chili.
Step 5 - Fill each avocado with the chicken avocado mix and top with cheese. Place in a muffin tin for help with stability.
Step 6 - Bake in the preheated oven until the cheese is melted, about 8 minutes. Remove from oven and top with more cheese, if desired. Top with plain Greek yogurt or sour cream, more salsa, and cilantro.
