Portobello Mushroom Burger

  • 4 portobello mushroom caps
  • 1/4 cup balsamic vinegar
  • 2 tablespoons olive oil
  • 1 teaspoon dried basil
  • 1 teaspoon dried oregano
  • 1 tablespoon minced garlic
  • salt and pepper to taste
  • 4 (1 ounce) slices provolone cheese

Whether or not you are a vegetarian, this portobello mushroom burger is a keeper! The portobello is often called the "steak" of mushrooms, and after making this recipe you will know why. The key to this recipe is the grilling so that it has that authentic grilled taste.

1. Place the mushroom caps, smooth side up, in a shallow dish. In a small bowl, whisk together vinegar, oil, basil, oregano, garlic, salt, and pepper. Pour over the mushrooms. Let stand at room temperature for 15 minutes or so, turning twice.

2. Preheat grill for medium-high heat.

3. Brush grate with oil. Place mushrooms on the grill, reserving marinade for basting. Grill for 5 to 8 minutes on each side, or until tender. Brush with marinade frequently. Top with cheese during the last 2 minutes of grilling.
