Mix the chili powder, sea salt, cumin, garlic powder, and black pepper in a small bowl. Sprinkle into the skillet, stirring to coat the onions and garlic for another minute.
Combine the drained black beans, roasted corn, shredded chicken, diced green chiles, chicken broth, salsa verde, and rice. Stir until well combined.
Bring the mixture to a boil for 2-3 minutes, then reduce the heat to low. Cover and let it simmer for 15 minutes.
Check the rice after 15 minutes; if firm, cover and cook a few more minutes.
Melt the shredded Monterey Jack cheese on top, cover, and let melt for 2-3 minutes.
Garnish with cilantro, sliced avocado, and red pepper flakes, then serve warm.
