In a 1-quart microwave-safe casserole combine the broccoli, carrot, green onion, and water. Micro-cook, covered, on 100% power (high) for 2 to 4 minutes or until vegetables are crisp-tender. Drain.
Brush one side of 3 tortillas with some of the oil. Place tortillas, oiled side down, on a baking sheet. Top with the cheese, vegetable mixture, and remaining tortillas. Brush tops with remaining oil. Bake in a 450 degree F oven about 6 minutes or until light brown.
To serve, cut each tortilla into wedges. Serve with sour cream, salsa, olives, and green onion, if desired. Makes 3 servings.
