1/4 cup (1 ounce) shredded part-skim mozzarella cheese
1 teaspoon olive oil, divided
1/2 teaspoon finely chopped fresh or 1/8 teaspoon dried rosemary
1/8 teaspoon coarsely ground black pepper
1 clove garlic, crushed
4 (5-inch) portobello mushroom caps
2 tablespoons fresh lemon juice
2 teaspoons low-sodium soy sauce
cooking spray
2 teaspoons minced fresh parsley
Instructions
Prepare grill.
Combine the tomato, cheese, 1/2 teaspoon oil, rosemary, pepper and garlic in a small bowl.
Remove brown gills from the underside of mushroom caps using a spoon, and discar gills. Remove stems; discard. Combine 1/2 teaspoon oil, juice, and soy sauce in a small bowl; brush over both sides of mushroom caps. Place the mushroom caps, stem side down, on grill rack coated with cooking spray, and grill for 5 minutes on each side or until soft.
Spoon 1/4 cup tomato mixture into each cap. Cover and grill 3 minutes or until cheese is melted. Sprinkle with parsley.
