Apple, Onion and Bratwurst (Crock Pot) from Food.com: I needed to make something for dinner and thought I'd try brats in the crock pot. They turned out great! All the kids had 2 and wanted more, LOL! I didn't have any beer so I tried pouring apple juice over it all and it turned out just as tasty. You could use beer if you like. No need to fire up the grill. It cooks all day while you're at work and is ready when you get home!
