Kalbi-Style Steak and Mushroom Lettuce Wraps

For all the Korean BBQ fans out there, this steak and mushroom version gets marinated in a kalbi-style marinade before getting tossed onto the grill. Use large king trumpet mushrooms since they can easily be sliced into thick pieces and hold up nicely on the grill. For a vegetarian main, skip the steak and increase the mushrooms to 1½ lb. (a mix of king trumpet and large clusters of maitakes or oysters works well). Serve with this spicy radish salad or store-bought kimchi and crisp romaine lettuce leaves for tableside wrapping.
