How to Make Creamy Portabella Gratin

  1. Preheat your broiler.

  3. Drain the broccoli and cauliflower thoroughly.
  4. While the vegetables cook, melt 2 tablespoons of butter in a large skillet over medium heat. Add 1 large portabella mushroom, finely diced, and 1/2 cup of diced red bell pepper. Sauté for 5 minutes, until softened.
  5. Transfer the cooked broccoli, cauliflower, and mushroom mixture to a 7-cup greased casserole dish.
  6. Microwave 4 ounces of spreadable cheese for 15 seconds, or until softened and easily pourable.
  7. Pour the melted cheese evenly over the vegetables.
  8. In a small bowl, combine 1/4 cup grated Parmesan cheese and 1 tablespoon of chopped fresh parsley.
  9. Sprinkle the Parmesan-parsley mixture over the cheese.
  10. Broil for 2-3 minutes, or until the cheese is golden brown and bubbly.
