1Boil the potatoes until tender. When they are cool enough to handle, smash them with a potato masher.
2Drain the sauerkraut well and meanwhile saute the garlic in melted butter. When the garlic releases its fragrance, add the sauerkraut and saute for a few minutes.
3Mix the sauerkraut with the potatoes in a big bowl. Use a food processor to chop the jalapeno and mozzarella. Mix everything together. Pour it all into an oiled baking pan. Sprinkle the parmesan on top and decorate with green beans. Bake for 1 hour at 375 degrees.
