This recipe always draws a crowd and it's perfect for summertime entertaining. It can be served in small slices as an appetizer, and can also stand alone as an amazing vegetarian entrée.
Coat the bottom of a large sauté pan with the oil.
Place the pan over medium heat, add 1 tortilla in the center of the pan (or 2 if they fit), and sprinkle it with an even layer of about half of the Mozzarella cheese. Now sprinkle an even layer of about half of the Cotija-chipotle mixture on top.
Remove from the quesadilla from the pan, place it on a clean, dry cutting board, and cut it into however many slices you'd like (depending on whether you're serving it as an appetizer or main course.) Repeat the above, if you didn't do both quesadillas at once.
