2. Sauté garlic and onion in large skillet. Add spices and sweet potato, mix well. (Add a little water if it's too sticky.) Turn burner very low to keep warm without scorching.
3. Meanwhile, preheat oven to 400°F. Oil a large baking sheet, then place 6 tortillas on it. Thinly spread filling on each. Layer slices or dollops of cheese and shredded greens. Top with a tortilla and brush a little oil on top.
4. Bake until browned and crisp, about 10-15 minutes. Cut into wedges and serve.
