I saw the pics, I didn't have crab meat, but the pictures, they inspired me. To make green bean casserole stuffed mushrooms. I made a bunch and wrapped half of them with bacon. 6 people easily put down almost 10 each! Everyone raved about them and a vegetarian friend was mindblown elbowing people to get more of them. There were none left.
I diced up the stems mixed them back in with some cream of mushroom and french cut green beans that I cut down a little more, and some french onions. Top with more onions. Bacon optional but awesome. Grill indirect on a weber kettle.
Thanks for the inspiration Larry!
