Portabellas are a large dark mushroom that lends itself well to the grill. These are best marinated ahead of time for at least 3 hours, preferably overnight.
6 large Portabella mushrooms
1 cup teriyaki sauce
4 cloves fresh garlic, crushed and chopped
Remove the stems from the mushrooms and place the caps into a shallow pan or bowl for marinating. Allow the garlic to set in the teriyaki sauce for an hour or two before using. Pour the sauce over the mushrooms and allow to marinate for at least 3 hours prior to cooking over a hot grill. Marinating them overnight under refrigeration is preferred. Grill these for about 4 minutes a side and serve while hot.
