Preheat the oven to 350 F.
Cook the ground beef along with the onion, garlic, and bell pepper in a large skillet over medium-high heat, until no longer pink. Add the tomato paste, cumin, coriander, parsley, chili powder, and red pepper flakes.
Place the rice, black beans, corn, meat mixture, green onions, and half of the shredded cheddar in the baking dish. Pour the chicken broth over everything and stir until all ingredients are well combined. Cover with foil and bake for 35 minutes. Remove the foil, add the remaining half of the cheese, and bake for 10-15 minutes or until the cheese is melted and bubbly.
