Portobello Burger with Mozzarella W
ho doesn’t love a good hamburger? I know I do! But I also love going meatless and really enjoy these Portobello Burgers, especially with pesto mayo and mozzarella, so good!! These are a variation of this Grilled Portobello Mushroom Burger recipe. I marinate and grill the mushrooms and top them with mozzarella, grilled red onions, roasted peppers, and an easy pesto mayonnaise sauce. For some other veggie burger ideas, try my Spicy Black Bean Burgers and Houston’s Veggie Burgers.
