Season the chicken breasts with olive oil, chili powder, cumin, paprika, salt, and pepper. Make sure to coat them evenly.
In a medium saucepan, bring 2 cups of chicken broth to a boil. Add the brown rice, reduce the heat to low, and cover. Cook for about 45 minutes, or until the rice is tender and the liquid is absorbed.
Heat a grill pan over medium-high heat. Once hot, add the seasoned chicken breasts and cook for 6–7 minutes on each side, or until the internal temperature reaches 165°F (74°C). Remove from heat and let rest for a few minutes before slicing into strips.
In each serving bowl, layer a scoop of cooked brown rice, followed by black beans, corn, diced tomato, and grilled chicken strips.
Top with diced avocado, shredded cheddar cheese, and a sprinkle of fresh cilantro.
Serve immediately with a lime wedge on the side, and optionally top with sour cream and salsa for added flavor.
Notes
Optional toppings include sour cream and salsa for added flavor.
