The portobello mushroom burger — the ubiquitous vegetarian summer picnic meal — isn’t really a burger at all. Which is to say it isn’t chopped meat formed into a patty, but rather a food found in nature with a natural hamburger bun size and shape. It’s perfect, really. Thank you, nature, for a food that’s shaped like a sandwich and requires virtually no work to prepare.
Bobby Deen’s Monster Mushroom Burger is one such “burger” that will let you picnic with your pals without having to participate in the pressing together of raw meat into patties. Giant, bun-sized portobello mushrooms are marinated in oil and vinegar, grilled and layered on a bun with a creamy herbed yogurt sauce, arugula, tomato, onion and roasted red peppers. If you’re inclined, add a slice of provolone or a smear of goat cheese and make it a cheese “burger.”
