Tortilla chips

1. A Mexican tortilla is unleavened round bread that is thin and flat. They are made from corn or wheat flour and baked on a griddle called a comal. The tortilla, which is similar to a sandwich, can be eaten plain or used as a food wrap for other foods, such as meat, poultry, seafood, cheese, beans, onions and peppers. Different sizes are available and they can be found in most grocery stores and ethnic markets. 2. Spanish tortillas are quite different from the Mexican tortilla in that they are a thin omelet containing potatoes, and other ingredients, such as onions, peppers, mushrooms, asparagus and tuna.
