Vegetable oil spray
8 ounces sliced fresh mushrooms
1/2 medium onion, thinly sliced and separated into rings
1 teaspoon bottled minced garlic
3 tablespoons chopped fresh cilantro
3 8-inch whole-wheat flour tortillas
6 tablespoons shredded low-fat Monterey Jack cheese with jalapeqo peppers or low-fat cheddar cheese
Preheat oven to 350 degrees F. Spray a large skillet with vegetable oil. Cook mushrooms, onion and garlic in skillet over medium heat until onion is tender, about 5 to 7 minutes. Stir in cilantro and remove from heat.
Arrange one-third of the mushroom mixture on half of one tortilla. Sprinkle with 2 tablespoons of the cheese. Fold the other half of the tortilla over cheese. Place on a baking sheet. Repeat with remaining ingredients to make 3 quesadillas total.
Bake quesadillas about 5 minutes, or until filling is hot and cheese melts. Cut each quesadilla into 4 wedges. Serve warm with salsa if desired.
Spray a microwave-safe casserole with vegetable oil. Add mushrooms, onion and garlic. Cook, uncovered, on 100% power (high) for 5 to 7 minutes, or until onion is tender, stirring twice. Stir in cilantro.
Assemble quesadillas as directed above and arrange them on a microwave-safe plate or platter. Cook, rotating plate once, uncovered, on 100% power (high) for 1 to 2 minutes, or until filling is hot and cheese melts.
