This post has the recipe for homemade vegetarian/vegan multigrain tortillas
Tortillas are the most versatile basic component of Mexican cuisine. Something like the Indian roti, only tortillas are used in many more ways than a roti is in Indian cuisine.
Traditionally tortillas are made with corn / maize flour with ample lard worked into the dough to keep the tortillas utterly soft. Soft tortillas are used as a base for quesadillas where a variety of fillings plus cheese are stuffed between two tortillas and the whole ‘sandwich’ is grilled / shallow fried on a griddle.
