01 - Heat a large skillet over medium-high. Cook ground beef, breaking up with a spoon, until browned and fully cooked, 5 to 6 minutes. Drain excess fat if needed.
02 - Add diced onion, red bell pepper, and zucchini to the skillet. Cook, stirring occasionally, until vegetables soften, about 3 to 4 minutes.
03 - Stir in minced garlic and cook until fragrant, approximately 30 seconds.
04 - Incorporate corn, diced tomatoes with their juice, beef broth, cooked rice, paprika, cumin, oregano, black pepper, and salt. Stir thoroughly to combine.
05 - Reduce heat to medium, cover, and simmer for 10 minutes, stirring occasionally, until vegetables are tender and flavors meld.
06 - Uncover and evenly sprinkle shredded cheddar cheese over the skillet contents. Cover again and cook for 2 to 3 minutes until cheese is melted.
07 - Remove from heat. Optionally garnish with chopped parsley or cilantro. Serve hot.
