Our instructions state to warm the tortillas in the microwave. This is just to get them pliable enough to fold without tearing. If you store your tortillas in the pantry as opposed to the refrigerator, you may skip this step.
This is basically a quick microwave and stovetop type meal. Alternatively, you can place burritos in a 13x9 baking pan, top with enchilada sauce and cheese and bake uncovered for 15-20 minutes in a 350 F oven, or until cheese is melted.
