Flautas or flute shaped tacos are perfect when feeding a large numbers of guests. If you are having guests over, you can always make the flautas in advance. You can store the unfried tacos in the freezer (without their toppings) and use them when you need. Or, you can fry the tacos, and keep them warm in the oven until you are ready to serve them…just add the toppings at the last minute.
