Take your favorite mushroom (we went with Crimini). Bag them up in your favorite marinade for a minimum of four hours, the meatier the mushroom the longer it can take a marinade, Criminis can go all night.
We went with a mix of Bragg's, Teriyaki sauce and garlic.
After a good soak, slip them all into a grill basket and put them in a heated grill for 10 minutes, turning half way through.
Enjoy these as is as a side dish or on top of a good boca or bean burger!
