Kielbasa and Sauerkraut

For lunch today I am eating Kielbasa and Sauerkraut. I'm sure you all really wanted to know this, but I'm sharing because of all the left overs I eat, this might be the best. Why?

1. It retains all of its flavor. 
2. It does not get weird when you re-heat it. 
3. Every time I make it I have enough food to feed myself at least three or four times after the first meal.
4. This past time I put apple in it, which makes it even better.
5. I love mixing mashed potatoes and sauerkraut together, peas are good too (although I don't have those today).
6. It reminds me of home. I might not be German, but we love Sauerkraut... weird I know.

I'm sure that there are a ton of other reasons why I love it so much that I just can't think of at the moment. But the best part of making it or even re-heating it is that everyone knows what you made. My current roommates don't mind the smell. Others have wrinkled their noses at me and thought me generally crazy. I don't really mind.

So what are everyone's favorite foods for Lunch? Or maybe a better questions, what is your favorite leftover to eat?
