01 - Heat a large skillet over medium-high heat. Add ground beef and break it up with a spoon. 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, until vegetables begin to soften, about 3 to 4 minutes.
03 - Stir in minced garlic and sauté for 30 seconds until fragrant.
04 - Add frozen corn, diced tomatoes with their juice, beef broth, cooked rice, paprika, ground cumin, oregano, black pepper, and salt. Stir thoroughly to blend flavors.
05 - Reduce heat to medium, cover skillet, and simmer for 10 minutes, stirring occasionally until vegetables are tender and flavors meld.
06 - Remove the lid and sprinkle shredded cheddar cheese evenly over the skillet contents. Cover again and allow cheese to melt for 2 to 3 minutes.
07 - Remove from heat, garnish with chopped parsley or cilantro if desired, and serve immediately while hot.
