1 portobello mushroom, stem removed
1 tablespoon olive oil
1 teaspoon red wine vinegar
1 clove garlic, thinly sliced
1/4 shallot, thinly sliced
salt and pepper to taste
1/2 roasted red pepper, cut into strips
3 cups arugula leaves
1 ounce grated Romano cheese
1 tablespoon Greek salad dressing
Preheat oven to 425 degrees F (220 degrees C). Line a baking sheet with a piece of aluminum foil.
Brush the mushroom on both sides with olive oil and place gill-side up onto the baking sheet. Drizzle with any remaining olive oil, and the red wine vinegar. Sprinkle with sliced garlic and shallot; season to taste with salt and pepper. Top with the piece of roasted red pepper, and wrap the foil tightly around the mushroom.
Bake in preheated oven until the mushroom is tender, about 30 minutes.
Toss the arugula with Romano cheese and salad dressing. Place onto a plate and top with the hot mushroom and pepper. Dig in!
