I missed Oktoberfest with this post (since technically Oktoberfect is in late September / early October) but this is still a great appetizer year round! Perhaps even for your upcoming Halloween party?!
I made this recipe: Sauerkraut with Kielbasa Sausage from Epicurious. Then instead of serving it as a meal I sliced the sausage, topped it with the sauerkraut, and then ran a heavy duty toothpick through both for a tasty-slightly messy-one-bite combo.
I hope you are having a great week!
