Introduced in 2005, Arby's Corned Beef Reuben has been a staple on the menu for two decades, but if you're looking to change things up, try swapping the corned beef for turkey.
Using Arby's roast turkey, which is seasoned with brown sugar and browned in oil for more flavor, takes the sandwich in a lighter direction while still packing in loads of flavor.
It's also a good substitution if you want a lower-fat and slightly lower-sodium. On average, 3 ounces of deli turkey has about 698 milligrams of sodium and 3 grams of fat.
Comparatively, if you take a look at the 3-ounce serving size of corned beef, it can have as much as 910 milligrams of sodium and over 16 grams of fat.
