Preheat the oven to 400F.
In a small bowl, combine all of the seasoning ingredients.
Add onion, red bell pepper, uncooked rice, and the seasoning into a 9x13 baking dish and stir to combine.
In a large bowl, combine chicken broth, green chilies, olive oil and tomato paste.
Pour the mixture into the baking dish and stir to combine.
Add in corn, black beans, and chicken. Mix to combine well.
Now, cover the baking dish with foil and bake in the oven for 65-70 minutes.
Remove the baking dish from the oven, remove the foil, and cover with shredded cheddar.
Bake in the oven for 5-10 minutes until the cheese melts and turns slightly golden.
Allow to cool for 5-10 minutes. Top up with cilantro, green onion, avocado, and salsa before serving.
