I am sharing my kitchen secret with you. I first read the small paragraph in Barbara Kafka's Microwave Gourmet about the possibilities of achieving sauteed mushrooms quickly in the microwave without a drop of butter. Then I began preparing my Portabello mushrooms this way to top my signature pizza (have you ever noticed that if you pile a lot of toppings on a pizza, it's hard to cook everything through?). I admit I use dry sherry almost as much as I use olive oil! One giant Portabello mushroom (5 -6 diameter) yielded 2 cups raw mushroom slice halves, which yielded 1 cup sauteed mushrooms for my pizza. These would also make a wonderful accompaniment to steaks or burgers, or omelets, or on other veggies...
