Lay out tortillas on a work surface. Sprinkle 1⁄4 cup cheese over half of each tortilla. Top with 1⁄4 cup vegetables. Fold the other half of the tortilla over the filling.
Spray a large sauté pan with cooking spray. Heat the pan over medium heat until hot. Place two tortillas side by side in the pan. Cook for 1 to 2 minutes on each side until cheese is melted. Transfer the tortillas to a cutting board and cut each into three wedges.
Keep warm in the oven while you cook remaining tortillas, two at a time. Top tortillas with salsa, guacamole, and sour cream.
