Grilled Portabello Burgers
4 large portabello mushrooms, stems removed
1/4 cup balsamic vinegar
1 Tablespoon olive oil
1 Tablespoon dried basil
1 teaspoon dried oregano
1 garlic clove, minced
condiments of your choice: avocados, tomatoes, sprouts, ranch dressing, onions, cucumbers, etc.
4 ciabatta rolls
Wash portabellos by using a damp paper towel and rubbing the caps clean. Set in a shallow pan.
Combine the remaining ingredients in a small bowl. Pour marinade over mushroom caps. Let sit for 15 minutes, flip the mushrooms over and marinate for an additional 15 minutes.
Once finished, place on a hot grill (on an electric grill, I use medium high heat), gill side down. Grill for about 15 minutes on each side.
Melt some smoked provolone over the top of each cap.
Serve on a toasted ciabatta roll with condiments of your choice.
