With Memorial Day falling on a Meatless Monday, it may seem like there are only two options when it comes to eating at today's barbecues: 1. Forgo vegetarianism and perhaps embrace a Meatless Tuesday instead. 2. Be relegated to the buffet's potato and pasta salads simply to maintain a meat-free plate. But it turns out that those aren't your only choices. You can indeed dig into to a hearty grilled dish at today's picnic — and at bashes all summer long — by opting for a mushroom burger.

Every bit as hefty as a beef burger, Food Network Kitchen's Grilled Portobello Burger with Onion Jam (pictured above) boasts the signature charred flavor you crave from grilled meats. And since these earthy portobellos are coated in a garlic-balsamic oil before cooking, they're full of satisfying flavor too. To round out the mushrooms and add even more bold taste and textures to this between-the-bun creation, pile on the toppings, including soft and sweet honey-laced onions, crisp lettuce, and horseradish-spiked yogurt for a light yet creamy finish.
