01 - Heat a large skillet over medium-high heat. Add ground beef and cook, breaking it up with a spoon, until browned and cooked through, about 5 to 6 minutes. Drain excess fat as needed.
02 - Add diced onion, red bell pepper, and zucchini to the skillet. Cook for 3 to 4 minutes until vegetables begin to soften.
03 - Stir in minced garlic and cook for 30 seconds until fragrant.
04 - Add frozen corn, diced tomatoes with 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 have melded.
06 - Remove the lid and evenly sprinkle shredded cheddar cheese over the skillet. Cover again and let the cheese melt for 2 to 3 minutes.
07 - Remove from heat, sprinkle with chopped parsley or cilantro if desired, and serve immediately.
