In a medium skillet over medium heat, brown the ground beef for about 8-10 minutes until fully cooked. Drain excess grease, sprinkle in taco seasoning, add water, and simmer for 5 minutes until thick.

While the beef simmers, heat large flour tortillas in a dry skillet over low heat for about 30 seconds on each side, or wrap in a damp paper towel and microwave for 20-30 seconds.

Spread a layer of cooked white rice in the center of a warm tortilla, followed by seasoned beef mixture, nacho cheese sauce, chipotle sauce, sour cream, cheddar, and mozzarella cheese.

Preheat a large skillet on medium heat, add butter or oil, place burrito seam-side down, and grill for 3-4 minutes until golden brown. Flip and grill other side for another 3-4 minutes.

Remove the burrito from the skillet, cut in half diagonally, and serve warm with your favorite salsa, guacamole, or dipping sauces.
