Remove from the heat and stir in the cilantro and/or basil.Meanwhile, make the chipotle sesame sauce by stirring together all ingredients in a glass jar. Lay the tortillas flat on a clean counter. On top of 2 tortillas, evenly layer the cheeses and broccoli/zucchini, drizzle with chipotle sauce, then place the remaining 2 tortillas on top.Heat olive oil in a large skillet over medium heat. When the oil shimmers, place the quesadillas, one at a time, into the skillet and cook until golden on each side, about 4-5 minutes per side. Serve topped with avocado, yogurt, and chipotle sauce.
