Because of their sturdy texture and meaty flavor, portabello mushrooms lend themselves to breading and frying. Or you can try roasting them, which saves fat and calories.
Make sure the mushrooms brown evenly by arranging them in a single layer in a large baking pan and lightly spraying them with cooking spray. The mushrooms are best served hot--toss them at once with the Parmesan so it melts a little.
The light red sauce, served on the side, also keeps this dish’s fat and calories low.
