In a shallow dish, whisk together oil, vinegar, garlic, 1 teaspoon salt, and 1/4 teaspoon pepper. Add bell pepper and mushrooms; toss gently to coat. Marinate at room temperature for 30 minutes (or refrigerate, up to overnight).
Heat grill to medium; lightly oil grates. Grill bell pepper, skin side down, until blackened, about 10 minutes; remove from grill. When cool enough to handle, remove and discard skin; set bell pepper aside. Grill mushrooms, covered, until lightly charred and tender, 3 to 4 minutes per side.
Dividing evenly, top bottom half of each bun with bell pepper, mushrooms, goat cheese, and lettuce. Close burgers, and serve immediately.
A large shallow dish allows the marinade to evenly coat the vegetables. Portobello burgers are nice and juicy because the mushroom caps underside thirstily absorbs the marinade.
I am always looking for whole food recipes to pin and share and try with my 90/10 Nutrition Challenge Groups (www.tribasetraining.com/nutrition) and this is one that worked perfectly. They are messy but very tasty. And, to the question below, I don't think it is necessary...just makes them a bit messy...but that is part of the fun. ;)
Mine is a question rather than a review. I was taught to remove the dark underside of the mushroom because it becomes "muddy" when it's cooked. I see they are still there in your picture. Do you disagree then? Thank you.
Amazing! I did a test run because I'm having vegetarian dinner guests this weekend. Despite being a dedicated carnivore, I might actually choose these *over* meat from time to time.
Very easy, tasty and quick. Marinated the mushrooms for the afternoon and grilled them on the Foreman grill - delicious. My 5 year old loved it.
