My mom makes a corn, sauerkraut, and hashbrown/potato dish that I love. I had some spaghetti squash I needed to get rid of and was craving her dish so I tried to use the squash in place of the potatoes. Worked great and has the same flavor. It may sound like an odd combination of flavors, but it works and it's so good for you too! I've also used parmesan or any shredded cheese in place of the feta.
