How do you cook mushrooms?
roast them with a lil oil and or butter, tyme, or some other hard herbs, add cheese like cheader or blue cheese is nice amd pepper, pepper loves mushies
saute them whole (if they are button muchrooms) or sliceed if they are bigger, but with feild mushies i tear them as it looks rustic, with olive oil, lil butter, garlic and or onions salt and pepper, herbs likle tyme and even with bacon or parma ham and make sure as much water comes out of em as possible and this intencifes the flavors,
(similar to NO.2) but add cream and chicken or vegi stock and reduce it, put it on steak or pasta :D
You can slice them up and saute them in oil...If you like onions add those too they are good on top of steak.
