Peel the mushrooms; brush away any dirt before you cut away the stems. Combine the oil, lemon juice, garlic, fresh herbs, salt and pepper to make a marinade. Add the mushrooms and the sliced mozzarella; marinate at room temperature for about 1 hour.
Grill the mushrooms over hot coals for about 2 min on each side. Remove from the grill and allow to rest for 5 minutes Serve the mushrooms on lightly toasted Kaiser rolls with the lettuce, sliced tomatoes and marinated mozzarella cheese. Cut each roll into quarters and serve.
