I have a potluck to go to next week and would like crock pot ideas?

Several things come to mind, but I'm thinking Spaghetti! Put your ground meat or turkey italian sausage, onion, spices, tomatoes and oil in your crock pot and let it cook all day. When you get home, boil up some pasta and mix. If it helps, you can cook the pasta while you're embling your crockpot sauce. Drain and refrigerate, then add later.
