For a vegetarian option, consider adding roasted vegetables like bell peppers, zucchini, or sweet potatoes to the filling. To reheat, remove the burrito from the freezer and microwave for 2-3 minutes, or until heated through. Alternatively, bake in a preheated oven at 350°F (175°C) for 20-25 minutes. Customize your burritos with your favorite toppings, such as sour cream, guacamole, or hot sauce, after reheating.
