Microwave mushrooms then throw them into the compost!

Start with butter, some garlic, and a dash of red wine if you want really wonderful mushrooms with the meal.

I have some dried mushrooms (an experiment) and they're okay to reconstitute then add to dishes. If I find them inexpensive at my gourmet warehouse last-chance store I usually buy and slice and lightly fry in butter or olive oil then freeze in small containers.

Steaming seems to leave the veggies in better shape, and when I store any leftovers (because I try to fix enough for a couple of uses) then I pour the remaining liquid over them. The dogs love to drink the leftover veggie liquid when the container is empty.
