Portobello Burger with Mozzarella
Who 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.
