In a large zip-top bag, combine the olive oil, lime juice, paprika, cumin, chili powder, garlic powder, onion powder, oregano, salt, and pepper.
Add the chicken breasts to the bag. Seal and shake until the chicken is evenly coated with the marinade.
Refrigerate for at least 30 minutes, or up to 4 hours for deeper flavor.
Heat a grill pan or outdoor grill over medium-high heat.
Remove the chicken from the marinade and grill for 5–7 minutes per side, or until the internal temperature reaches 165°F (74°C).
Transfer the chicken to a cutting board and let it rest for 5 minutes before slicing.
In a medium bowl, combine the cooked brown rice, lime juice, chopped cilantro, sea salt, and black pepper. Toss until evenly mixed.
To assemble the Grilled Chicken Burrito Bowl, divide the mixed greens between two serving bowls.
Top each bowl with sliced grilled chicken.
Add the cilantro-lime rice, black beans, corn, cherry tomatoes, avocado slices, diced red onion, and Greek yogurt.
Garnish with sliced jalapeño and additional fresh cilantro.
Serve immediately and enjoy.
