6 - 8 large Portabello mushrooms
1 Tbsp. olive oil
1 Tbsp.
soy sauce
2 cups fresh tomatoes, chopped
1 onion,
chopped
One quarter cup fresh cilantro, chopped
1 tsp.
fresh rosemary, chopped or one quarter tsp. dried
2 cloves
garlic, minced
1 Tbsp. fresh lemon or lime juice
One
quarter cup Parmesan cheese, grated
Remove gills from the under sides of each mushroom. Combine olive oil
and soy sauce and brush over mushrooms. Grill over medium-high heat
for several minutes per side. Meanwhile combine tomatoes, onion,
cilantro, rosemary, garlic, and lemon juice in a bowl and mix well.
Remove mushrooms from grill and pour sauce on the under side of each
mushroom and sprinkle with Parmesan cheese.
The Skinny: Leave off the Parmesan cheese.
