Makes 4 servings

Ingredients

  • 4 large portobello mushrooms
  • 1/2 (16 oz) pkg frozen spinach, thawed and squeezed dry
  • 4 oz horseradish cheddar cheese, thinly sliced or shredded
  • 1/4 cup balsamic vinegar
  • 4 kaiser rolls
 

Directions

1. Scrape off the gills (brown part) on the underside of the portabellas with a spoon. Drizzle balsamic vinaigrette over the mushrooms and rub in with your hands. (For best results, allow mushrooms to marinate for 5 minutes) Set oven to broil.
2. Place marinated mushrooms on a broiler tray or a rack on a baking pan. Broil on high for 7 minutes or until lightly browned. Flip and broil for an additional 3 minutes.
3. Remove mushrooms from oven, and flip so underside of mushroom cap faces up. Divide the spinach evenly between the mushrooms and top with the cheese. Broil for 1 min. or until cheese is bubbly and melted.
4. Remove from oven, and toast rolls under broiler. Assemble mushroom burgers and serve immediately.
 

Notes
