Tortillas are thin, flat pancakes of cornmeal or flour that are eaten hot or cold with a savory filling. In Spanish cooking, tortillas are actually thick omelets made of potatoes and other vegetables that are cut into wedges and served.
When making sandwiches, the Mexican tradition inspires me. I use store bought tortillas and look for ones that have the least amount of ingredients. When choosing gluten free, I like the texture and taste of the chickpea tortillas. (This is what I use for my Hummus Quesadillas).
