Create a delicious, south-of-the-border fiesta with these traditional Mexican dishes. Serve colorful Calabacitas (a zesty side dish of zucchini, corn, and chilies) with easy entrees like burritos, enchiladas, and tacos—made spicy or mild, according to your taste. And, ¡ole! — For dessert there's Tres Leche Cake, a moist white cake sweetened with a rich, milky sauce.
