Notes
If you want to know how to make homemade corn tortillas, we love this Simply Recipes tutorial.
If you use brown rice instead of white rice, it can significantly alter the taste and cook time of the recipe.
For casserole toppings, we suggest the following: avocados, pico de gallo, shredded lettuce, sour cream, salsa, or chopped jalapeños. Please note that toppings can alter the nutritional information of the recipe.
To store leftovers, once the casserole has cooled completely, place in a shallow, airtight container for 4 to 5 days.
