Season the chicken breast evenly with the cumin, chili powder, sea salt, and black pepper.
Heat the olive oil in a medium skillet over medium-high heat.
Add the chicken to the skillet and cook for 5-7 minutes per side until golden brown and the internal temperature reaches 165°F.
Remove the chicken from the pan, let it rest for 3 minutes, then slice into thin strips.
In the same skillet, add the sliced bell peppers and sauté for 3-4 minutes until they are tender yet still have a slight crunch.
In a small bowl, toss the cooked brown rice with the lime juice and fresh chopped cilantro until well combined.
Warm the black beans in a small saucepan or microwave until heated through.
To assemble, place the cilantro-lime rice in a bowl and top with the sliced chicken, sautéed peppers, and black beans.
Garnish the bowl with the fresh salsa and enjoy immediately.
