Whenever the word "veggie" modifies "burger," many people taste skepticism more than anything else.
While it's true that many vegetarian burgers are nothing more than mushy patties of ground-up produce, this portobello burger with sun-dried tomato mayonnaise is a burger of a different class.
Marinated and grilled just right, a large portobello mushroom cap can be just as toothsome and "meaty" as the real deal. And when you add accouterments such as char-grilled red onion and red bell pepper, plus a slathering of savory sun-dried tomato mayo, you just might turn a meat eater into a vegetarian. At least until the next meal.
Portobello Burger With Sun-Dried Tomato Mayo
For the mayo:
• 1/2 cup reduced-fat mayonnaise
• 2 tablespoons prepared sun-dried tomato pesto
• 1 teaspoon lemon juice
For the burger:
• 1/3 cup red wine vinegar
• 1/4 cup extra-virgin olive oil
• 2 cloves garlic, minced
• 1 teaspoon Dijon mustard
• 1/2 teaspoon salt
• 1/2 teaspoon ground black pepper
• Four 5-inch round portobello mushroom caps
• Four 1/2-inch-thick slices of red onion, cut from a large red onion
• 1 yellow or orange bell pepper, quartered lengthwise and seeded
• 4 kaiser rolls, split
• 1 cup baby arugula
In a small bowl, stir together the mayonnaise, sun-dried tomato pesto and lemon juice. Cover and refrigerate until serving time.
In a large bowl, whisk together the vinegar, oil, garlic, mustard, salt and pepper. Add the mushrooms, onions and peppers, turning to coat with the marinade.
Heat a gas grill to medium-high or light a charcoal fire.
Remove the vegetables from the marinade, letting any excess drip off. Reserve the marinade. Grill the vegetables until they're browned on both sides and tender, about 5 minutes per side, brushing once with additional marinade during cooking.
Meanwhile, toast the rolls at the edge of the grill or in a toaster.
To assemble the burgers, divide the arugula among the 4 roll bottoms. Top with onions and peppers. Set the mushroom caps on top. Spread a quarter of the mayo on each roll top and set on top of the mushrooms.
