Bring a large pot of water to a boil. Cut peppers in half through length (top to bottom), seed and devein peppers, then boil 4 – 5 minutes (fully immersing them in the water), just until tender. Drain well and align in baking pans, set aside.
Heat 1 Tbsp oil in a large and deep skillet over medium-high heat. Add onions and saute until golden about 5 minutes, then add garlic and saute 30 seconds longer, transfer onion mixture to a plate. Add remaining 1 Tbsp oil skillet, and add chicken, sprinkle with 1/2 tsp chili powder, 1/2 tsp cumin, the paprika and season with salt and pepper. Cook, stirring occasionally, until cooked through, about 5 minutes. Reduce heat to medium-low, add tomatoes, onion mixture, black beans, corn, cooked brown rice, remaining 1/2 tsp chili powder, 1/2 tsp cumin cumin, cilantro, lime juice and season with salt and pepper to taste. Cook just until heated through.
Add a heaping 1/2 cup of the mixture to each pepper half (and slightly press as filling to fit). Pour enough water into bottom of baking dishes to reach 1/8-inch in height (careful not to pour it in peppers). Cover baking dishes with foil and bake 30 – 35 minutes, until peppers are soft. Remove from oven, sprinkle tops evenly with cheese then return to oven to bake until cheese has melted, about 3 minutes longer.
