Your favorite reuben sandwich filling teams up with versatile crescent roll dough to make these yummy bite-size appetizers. It's an excellent way to use either deli corned beef or leftover corned beef. All you need is some sauerkraut, shredded cheese, and a bit of thousand island or russian dressing. Make them as a snack for a family tv night or a game day party. Feel free to make some changes to the filling, if you like. Lean pastrami, ham, or roast beef are very good in these snacks as well. Or, for a rachel sandwich, use a well-drained coleslaw instead of sauerkraut. Swiss cheese is traditional in reuben sandwiches, but feel free to use another kind of cheese. Mozzarella, mild cheddar, muenster, and gruyere are good options. We've provided our version of homemade thousand island dressing, but please fee free to use a bottled dressing, if that's your preference.
