Heat a large pot over medium heat, add cooking oil, then add the onion and peppers. Allow the vegetables to start to wilt, 5-7 minutes. Add the chicken and cook till it is about half cooked.
Sprinkle the spices on and allow to become fragrant, then pour in the chicken broth and add the green chiles.
Bring to a low boil and add the rice and black beans.
When the rice is almost done, add the corn and allow to warm while the rice finishes cooking.
Serve with chopped jalapenos, cilantro, sour cream, cheddar cheese, lime wedges … whatever you want, if anything.
