A chalupa is a Mexican dish similar in a lot of ways to a taco or tostada. The shell of a chalupa is it’s most discerning feature. It is made from corn masa dough that has been molded and deep fried. Into this crisp shell is placed chicken or pork, onion, chipotle, cheese, and different types of salsa and chili sauce. Chalupas are also served in Taco Bell in a slightly different form. Instead of deep fried masa shells, they use a wheat flour-based shell similar to fried dough.
