Portobello Mushroom Burger - 4 stars

this was QUITE a yummy treat. i'd rate it five stars, except that i was still starving after eating it. i'm totally a carnivore, i'll be honest. :-) i believe i had potato chips and a small salad with it. if i made this again, i'd make a bigger salad with extra protein ingredients, like garbanzo beans and avocado and some bacon, to go with the burger. or i could make sweet potato fries... mmmmm....

anyway - it was a really easy meal, and the jumbo kaiser rolls were perfect with it. there wasn't quite enough marinade for my mushroom caps, so i'd increase it by 1/2 next time. doubling it would be too much.

enjoy!

Ingredients

Marinade:

• 2 tablespoons brown spicy mustard
• 3 tablespoons balsamic vinegar
• 1/2 cup olive oil
• 1 teaspoon kosher salt
• 1/2 teaspoon freshly ground black pepper
• 1 teaspoon hot sauce
• 4 portobello mushroom caps
• 4 slices Gouda cheese
• 1/2 cup mayonnaise
• 4 hamburger rolls
• 1 red onion, sliced
• 4 leaves butter lettuce
• 1 tomato, sliced

Directions

Combine marinade ingredients. Place caps into a baking dish and pour marinade over top. Use a brush to make sure all caps are covered with the marinade. Set aside and let marinate up to 2 hours.

Remove the portobellos from marinade (do not discard marinade) and place gill side down on a preheated gas, electric or charcoal grill over medium-high heat. Grill 3 to 4 minutes per side. Top each cap with cheese 2 minutes to melt before they are finished grilling.

In a medium bowl combine 1/2 cup mayonnaise and 2 tablespoons of the marinade.

Spread the flavored mayonnaise onto each bun and top with portobellos. Serve with sliced onion, lettuce and tomato.
