**Cook the chicken**
Heat olive oil in a large skillet over medium heat. Add the diced chicken and season with chili powder, cumin, smoked paprika, garlic powder, onion powder, and salt. Cook for 5–7 minutes, stirring occasionally, until the chicken is golden and cooked through. Remove from the skillet and set aside.
**Toast the rice**
In the same skillet, add a bit more oil if needed. Stir in the rice and toast for 1–2 minutes, until slightly golden.
**Combine ingredients**
Add the cooked chicken back to the skillet, along with black beans, corn, diced tomatoes (with their juice), and chicken broth. Stir well to combine.
**Simmer**
Bring the mixture to a boil, then reduce the heat to low. Cover the skillet with a lid and simmer for 18–20 minutes, or until the rice is cooked and the liquid is absorbed.
**Add cheese (optional)**
If using cheese, sprinkle it over the top and cover the skillet for 2–3 minutes until the cheese melts.
**Serve**
Fluff the rice with a fork and serve hot. Add your favorite toppings, such as avocado, sour cream, salsa, or chopped cilantro, and garnish with lime wedges.
