My wife threw this together a few months back, turned out fabulous.
A package of Italian sausage. (Brat, or ground)
A quart jar of stewed Tomatoes.
3 big Spuds.
Brown the sausage, (remove the oil if you want) Salt and pepper to taste. Add tomatoes and let simmer for about 30 minutes.
Peel and boil as many potatoes as you would like.
Mash the spuds.
Serve the sausage and tomatoes over the mashed potatoes.
