A vegetarian take on a classic summer grill favorite: burgers!


7 tablespoons
olive oil (divided)
5 tablespoons
red wine vinegar
1 1/2 teaspoon
oregano, dried
1 1/2 teaspoon
fennel seeds (ground or crushed)
1 pound
mushrooms, portobello
onion, red (thinly sliced)
bread, ciabatta
4 ounces
cheese, provolone (sliced)
4 ounces
lettuce, romaine
1 cup
tomato, sun-dried
1 clove
garlic (peeled)
1/4 cup
parsley, fresh
1/4 cup
basil, fresh
2 tablespoons
pine nuts
1/4 cup
cheese, parmesan (shredded)
1/2 cup
1 pinch
black pepper (ground)


Scrape out and discard the gills of each mushroom. Cut caps into ½-inch thick slices. In a small bowl, mix together the oil (5 Tbsp), vinegar, oregano and fennel, reserving 2 tablespoons. Place the sliced portobellos in the marinade for 20 minutes. Mix together the onion and remaining marinade in a small bowl and set aside. Place tomatoes, garlic, parsley, basil, pine nuts, olive oil (2 Tbsp) and Parmesan in a food processor and blend until the mixture is a spreadable paste, adding water as needed. Season to taste with pepper and set aside. Heat a large skillet over medium-high heat. Remove the mushrooms from the marinade and sauté for 5-10 minutes until just tender. Remove from heat. Season with salt and pepper. To assemble sandwiches, place provolone slices on the bottom half of each ciabatta roll, then divide the sun-dried tomato spread, sautéed mushrooms, marinated onions and lettuce evenly among the four sandwiches. Top with the other half of the roll and serve.
