In a large skillet over medium heat, add 1 pound of ground beef and cook for about 6-8 minutes, breaking it apart with a spatula until it's no longer pink. Drain any excess fat once cooked.

Stir in 1 packet of taco seasoning and 1 can of diced tomatoes (including juice) to the browned beef. Cook for about 3-4 minutes until heated through and fragrant.

Add 2 cups of cooked rice to the skillet, mixing well until every grain is coated. Cook for an additional 2-3 minutes to warm the rice through.

Sprinkle 1-2 cups of shredded cheese evenly over the mixture. Cover with a lid and let it cook for about 2-3 minutes on low heat until the cheese melts.

Remove the skillet from heat and prepare to plate your dish. Add optional toppings like chopped cilantro, sour cream, or sliced jalapeños.
