I first tried these at Octoberfest in Wichita. I have not found anywhere here that has them, but I do make them at home from their recipe.

1 lb ground beef
1/2 lb pork sausage
1 can drained sauerkraut
2 cans crescent dinner rolls
Salt and pepper to taste
Grated cheddar cheese (optional)

Brown beef and sausage and drain, add drained kraut and heat another 5 to 7 mins. Take pan off of stove to cool mixture.

Make 8 rectangles out of rolls, when mixture has cooled place on 4 rolls and top each with the other 4 rolls and pinch together edges. Cut small slits in top of rolls and bake for 15 to 20 mins. (Golden brown) in 350 degree oven.
You can add cheese on top in the last 5 mins of baking or put on top of mixture inside of roll.
