You won't find any queso in these "Spinach, Mushroom, & Black Bean Quesadillas" (page 127), but you will find a savory stuffed tortilla grilled to perfection, and they come together in no time flat. In today's culinary lingo, quesadilla is loosely defined as just about any filling you want, layered into a tortilla, and grilled in a skillet, with cheese no longer a strictly necessary ingredient. Omit the oil when sautéing the veggies (which also includes onions and garlic), and the filling will be completely McDougall friendly. Try to find a whole grain, no-oil added tortilla for the healthiest choice, such as the Ezekiel sprouted grain variety from Foods For Life. These tortillas make especially delicious quesadillas! Skip the oil when grilling the quesadillas by using a non-stick skillet - they will still brown very nicely, especially the Ezekiel brand tortillas, which include some natural oil from the sprouted seeds they contain.
