If you offer sandwiches as a catered option for your customers, they might be getting tired of the same classic options like turkey, ham, and roast beef sandwiches. Why not shake things up a little with some unique deli sandwiches? Some customers may still stick with the classics, but others will be glad to order something unique and different. To that end, here are three really unique deli sandwiches you can add to your catering menu:

The Cold Reuben

The classic Reuben is a hot sandwich made with sauerkraut, corned beef, and Swiss cheese. But this cold version is every bit as delicious. Choose soft rye bread cut into thick slices. On one side of the bread, place a few thin slices of deli-style corned beef. Spread the other side with some mayonnaise and then layer on a few pieces of Swiss cheese. Make sure you choose a very pungent Swiss cheese as the flavor is less intense when the cheese is cold, rather than melted. Put the sauerkraut between the meat and cheese so it does not make the bread soggy. Close up your sandwich and secure it with a toothpick.

Pizza Sandwich

If you're looking for a fun way to use leftover pizza, this is it! Cut two bread slice-size squares of cold, thin crust pizza. Place one crust-side down, and layer some provolone cheese, capicola, prosciutto, and sliced red onions on top of it. You can then drizzle the toppings with some balsamic vinegar and olive oil for a real Italian flavor, and finish with a few leaves of fresh basil. Cap it with your second piece of cold pizza, placing it cheese-side down. Once again, you're going to need a toothpick to hold this thick sandwich shut!

Ultimate Chicken Salad

This sandwich takes chicken salad to the next level. Mix up your own batch of chicken salad using the following ingredients:

• 2 cups shredded chicken breast meat
• 1/3 cup light mayonnaise
• 1 tablespoon apple cider vinegar
• 1/4 cup apple, cut into small pieces
• 2 tablespoons green onion, minced
• 1/4 cup walnut pieces
• 1/4 cup raisins
• 1 teaspoon honey

To assemble your sandwich, first place a piece of pumpernickel bread down on your work surface. Add some leaf lettuce and a slice of provolone, and then layer on the chicken salad. Top it with another slice of cheese, and this helps keep the top slice of bread from getting moist and then put on that top slice of delicious bread.
