Slow Cooker Sausage with Sauce

I made this last weekend and froze it for future use.  If it tastes half as good as it smelled when it was cooking, Chris and I are in for a real treat.  I had some leftover sausage left and put that in a saucepan with some tomato sliced (the sausage was sliced into medallions) and simmered it for 4 hours.  It made great pasta sauce.

8 links fresh Italian sausage
1 26oz. jar spaghetti sauce
1 green bell pepper, seeded and sliced into strips
1 onion, sliced

Place sausage links, spaghetti sauce, green pepper and onion into a slow cooker.  Stir to coat everything in sauce.  Cover and cook on low for 6 hours.  Serve on hoagie rolls or over rice.
