30 MINUTES OR LESS Pizzas without the excess calories!
Preheat oven to 450F. Lightly spray baking sheet with nonstick cooking spray, and set aside.
Combine oil and garlic in small bowl, and rub mushroom caps on all sides with mixture. Place caps, top side down, in circle on baking sheet. Season with salt and pepper. Arrange cheese, basil and tomato slices alternately in circle on top of mushrooms. Sprinkle with oregano, if using.
Bake about 3 minutes, or until cheese melts. Remove from oven, and serve.
Of course, you can always enjoy a Chianti with any dish that even resembles Italian food, but to truly enjoy the earthiness of the portobello mushrooms without overwhelming them, select a mild Oregon Pinot Noir, such as a King Estate or a Duck Pond.
