01 - Heat a large skillet over medium-high heat. Add ground beef, breaking it up with a spoon, and cook until browned and fully cooked, about 5 to 6 minutes. Drain excess fat if needed.
02 - Add diced onion, red bell pepper, and zucchini to the skillet. Cook, stirring occasionally, for 3 to 4 minutes until vegetables begin to soften.
03 - Stir in minced garlic and cook for 30 seconds until fragrant.
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 and cover the skillet. Let simmer for 10 minutes, stirring occasionally, until vegetables are tender and flavors meld.
06 - Remove the lid, evenly sprinkle shredded cheddar cheese over the mixture, cover again, and allow cheese to melt for 2 to 3 minutes.
07 - Remove skillet from heat. Garnish with chopped parsley or cilantro if desired. Serve hot.
