I made an improvised stuffed mushroom recipe this weekend (I saw the really large mushrooms in the store and just had to make stuffed mushrooms). I started with the basics...the chopped mushroom stems, a little garlic, onion, bell pepper and celery sauteed in lots of butter. Once it was melted down a bit (until the onions were clear), I added some plain breadcrumbs and a sprinkling of panko breadcrumbs for a tiny bit of crunch. Added some crab meat (the better quality stuff sold by the fish counter that is cooked, but tastes fresh, not the stuff in cans in the tuna aisle) and just let that warm through a bit. Oh, I added a little salt, pepper, oregano, basil, and garlic and onion powder while the vegetables were cooking...not a lot of seasoning, just a little (that's why I don't use seasoned bread crumbs, because I think they're over-seasoned).
Stuffed the mushrooms with the stuffing, sprinkled on a touch of finely grated parmesan reggiano, topped with a lightly sauteed (in olive oil) slice of eggplant (just to get it started cooking) a little tomato sauce (I was making that homemade too...yesterday was a big cooking day for me), and a bit more parmsan cheese.
Baked for about 30 min at 350 F. Very yummy! I winged it on the crab meat stuffing, but it tasted pretty much like I thought it should. The little bit of eggplant parmesan on top went with it really nicely.
