One of my friends shared this idea with us. We love it!! No recipe is really required.
You just take ground meat (beef, pork, chicken, turkey, etc could even be vegan stuff),
mix in the spices you like (salt and pepper work great)
Form Meatball sized balls of the mixture,
Flatten the meat to form a patty and put it inside a mushroom you have cut in half.
Place them on a lined cookie sheet.
and ... Bake ... We baked ours at 400 deg F. for about 20-25 minutes or until the meat was done to our liking.
The yummy juices from the meat cooked right into the mushrooms.
Then we just added what yummy extras we wanted like cheese, onion, tomato, avocado, etc. No need for condiments. They are yummy as is. AND... there is no need for a bun they are veggie high and carb low. Love It!
