Preheat oven to 350 degrees. In a skillet, brown sausage with onion over medium heat. Drain and add remaining ingredients. Mix well and cook in oven for 15 minutes.
Take out of oven after 15 minutes, stir and cook the another 15 minutes. I made this in an iron skillet and didn't cover it. You can easily combine the ingredients in a casserole dish to cook in the oven. Makes 4-6 servings.
