For a smoky flavor, grill the portobello mushrooms instead of broiling. Marinate for at least 30 minutes before grilling. Add a slice of provolone or mozzarella cheese during the last minute of broiling for a melted cheese topping. Experiment with different toppings, such as roasted red peppers, caramelized onions, or a sprinkle of feta cheese. For a vegan option, substitute the mayonnaise with a vegan alternative.
