  • Preparation
    Split the rolls in half horizontally, keeping them attached on one side so they open like a book. Spoon the mushroom mixture and spinach mixture on each roll. Spoon about a 2 tablespoons of the sauerkraut mixture and 2 tablespoons of Russian dressing on each sandwich. Add shredded or sliced cheese of choice (optional).

Cut the sandwiches in half and serve with salad or veggies with your favorite dip. Recommend white bean dip with garlic, lemon and herbs.
