Start by pounding your chicken breasts to an even thickness. This ensures they cook evenly and stay juicy. Season the chicken on both sides with 3/4 tsp kosher salt, 1/2 tsp cumin, 1/2 tsp smoked paprika, 1/2 tsp chili powder, and 1/4 tsp freshly ground black pepper.
In a large skillet, heat 2 tbsp olive oil over medium-high heat. Add the seasoned chicken breasts and cook for about 6-7 minutes on each side, or until the chicken is cooked through and no longer pink in the center. Remove the chicken from the skillet and set aside on a plate.
In the same skillet, add the chopped onion and red bell pepper. Sauté for about 3-4 minutes until they are softened. Then add the minced garlic and cook for an additional 1 minute, stirring frequently to avoid burning.
Stir in 1 tsp kosher salt, 1/2 tsp cumin, and 1/2 tsp chili powder into the vegetable mix. Add the jasmine rice, diced tomatoes, and 3 1/2 cups chicken broth. Bring the mixture to a boil, then reduce the heat to low, cover, and simmer for about 15 minutes, or until the rice is tender and has absorbed the liquid.
After the rice is cooked, stir in the black beans and corn. Nestle the cooked chicken breasts back into the skillet, cover, and cook for another 5 minutes until everything is heated through.
Sprinkle the shredded Monterey Jack cheese over the chicken and rice, cover the skillet again, and let it sit for about 3-5 minutes until the cheese melts beautifully.
To serve, scoop the chicken and rice onto plates or into bowls. Top with chopped avocado, a generous dollop of sour cream, and sprinkle with fresh cilantro. Serve with lime wedges on the side for a burst of zesty flavor.
