Set your oven at 400°F. Combine onion pieces, rice, bell pepper chunks, optional cayenne, and fajita seasoning directly into a 9x13 pan, then mix it all together.
02 -
In a measuring cup or a small bowl, whisk olive oil, tomato paste, chicken broth, and canned green chilies together until smooth.
03 -
Pour the liquid mix into the pan with the dry mix. Then toss in the chicken, beans, and frozen corn, and make sure it's all stirred evenly.
04 -
Seal the baking pan tightly with foil and put it in the oven for about 65-70 minutes, or until the liquid isn't visible anymore.
05 -
Take off the foil cover and sprinkle cheese across the surface evenly once it's out of the oven.
06 -
Place the pan back in the oven without foil for another 5-10 minutes, long enough for the cheese to melt and turn lightly golden.
07 -
After pulling it out of the oven, let it cool down for a bit, around 5-10 minutes. Add fresh cilantro, avocado slices, salsa, or green onion, if you'd like.
