Preheat oven to 350 degrees. In large bowl, mix beef and pork with breadcrumbs, egg, chili sauce, mustard, salt and pepper until well-blended. Shape into 2-inch balls (makes about 24 meatballs). Brown, half at a time, in oil in a large skillet; remove as they are browned with a slotted spoon and set aside.
Sauté onion and carrot in drippings in skillet for 5 minutes. Add caraway seeds, paprika and apple juice, and bring mixture to the boil. Stir in sauerkraut and apple. Turn mixture into a shallow 2-quart casserole; add meatballs and cover.
Bake for 30 minutes or until meatballs are cooked through. Remove cover, stir in sour cream and sprinkle with Swiss cheese. Continue baking, uncovered, 10 to 15 minutes, until cheese is melted and hot.
