How to Make Portobello Mushroom Tuna Melt

  1. Preheat your broiler to high.
  2. Brush the tops of 2 large portobello mushrooms with 1 tablespoon of olive oil.
  3. Place the mushrooms gill-side up on a rimmed baking sheet. Broil for 5-7 minutes per side, or until softened and slightly charred.
  4. While the mushrooms broil, prepare the tuna salad: In a medium bowl, gently combine 1 (5 ounce) can tuna (drained), 1/2 cup finely chopped celery, 2 tablespoons chopped fresh parsley, 1 tablespoon lemon juice, 1/2 teaspoon salt, 1/4 teaspoon black pepper, and 1 tablespoon olive oil.
  5. Remove the mushrooms from the broiler.
  6. Evenly divide the tuna salad among the mushroom caps.
  7. Top each mushroom with 1 slice of your favorite cheese (cheddar, provolone, or Swiss recommended).
  8. Broil for 1-2 minutes, or until the cheese is melted and bubbly.
  9. Serve immediately. Garnish with a tomato slice and your favorite greens (optional, serve on the side for less mess).
