1-1/2 cups sautéed onions*

3/4 tablespoon dried oregano
1/3 cup white or red horseradish
1-1/2 pound hearty Italian bread loaf, sliced horizontally
6 ounces Swiss cheese, sliced
2 cups mixed baby greens
6 ounces Colby cheese, sliced
1/2 pound roast beef, sliced
6 ounces Provolone cheese, sliced
1/2 cup sweet pickle chunks (optional)

Mix sautéed onions and oregano and set aside. Spread horseradish on the bread bottom then layer with the Swiss cheese, mixed greens, Colby, roast beef, Provolone, onions and, if desired, pickles; top with remaining half loaf; slice and serve.

*To sauté onions, cook four cups (equals 1-1/2 cups sautéed) onions on low with 2 tablespoons butter until browned.
