Before you can starting cutting the sausage into peices, you will need to take the casing off of them. I like to run my knife gently down the casing for easy take off. After you take the casing off, you will then need to cut the sausage into about 1 inch peices, or bigger depending on how big you like. Refer to the picture below on what size I cut them.
After you cut them, you will need to get back to your onions and peppers. You should then add the peppers into the same skillet as your onions. Add the speghetti sauce at this time as well. Cover the skillet and cook on low heat.
Now you will need to start browing the sausage, but make sure not to cook it all the way. Once you have browned all the sausage, add it to the onion and pepper sauce mix. Simmer until sausage is fully cooked.
While the sauce is cooking, you will need to cook up some rice. You can cook as much or as little as you like. By the time the rice gets done cooking, so should the sauce as well.
