  1. Preheat your oven to 400°F (200°C) and lightly grease a 9×13 casserole dish.

  6. Combine the cooked rice, vegetable mixture, and cheese sauce in the skillet, folding until everything is evenly coated. Season with salt and pepper to taste.
  7. Transfer the rice mixture to the prepared casserole dish. Top with the remaining cheddar and Monterey Jack cheese, then scatter the halved cherry tomatoes on top.
