My daughter is allergic to soy and is pescatarian, so we’ve found a good meatless source for her with mushrooms, but I haven’t come across any that is dehydrated and shelf stable. She uses a frozen kind. We have learned that it works great as a ground meat substitute when we make chili or tacos or things with a good amount of seasoning. If you know of something, I’m interested.
I eat a lot of ‘shrooms. I make canned marinated mushrooms, marinate them overnight and saute and serve with beef, chicken, whatever. Dice them with onions, saute and pop them in your gravy. Love ‘em. I’ll go through 3-4 pounds of them in a weekend. I’ll have to try them as a addition to ground beef.
Asian grocery stores sell big bags of dehydrated mushrooms for reasonable price. Oyster mushrooms, blank cloud, maitake and shitake are good ones to have.
