Tips for Cooking

Use Leftover Rice: This is a great recipe to use up leftover rice. If you don’t have cooked rice on hand, you can cook it while preparing the other ingredients.
Use Ground Turkey or Chicken: For a leaner option, you can substitute ground beef with ground turkey or chicken.
Add More Veggies: If you want to make the casserole even more nutritious, consider adding other vegetables like corn, zucchini, or mushrooms.
Make it Spicy: For a little heat, you can add some diced jalapeños or red pepper flakes to the beef mixture.
Customize the Cheese: Feel free to mix up the cheese; mozzarella, Monterey Jack, or a Mexican cheese blend would all work well.
