Cut up your kielbasa either long length slices or small bite size pieces.

Rinse potatoes well. Cut out any spots , sprouts etc . Cut into small bite size pieces. Rinse again if you like. You can do them larger but they will take longer to fry.

Peel off outside of the onion. Slice into rings , dice or slice half rings. Your choice or preference

In a frying pan add in your oil or butter. Turn heat up to medium or medium high. The higher you have the heat the quicker it will cook but can burn faster.

Keep an eye on this so it doesn't burn. Continue cooking until all of the potatoes are fully cooked. Stir/mix/flip continually throughout the whole cooking process.

Before this is done cooking , make sure that you cook anything else your having along with it and start them whenever you need to ie; rice can be done around the end of cooking this , macaroni and cheese will take longer so start that sooner etc .. this could also work as a side if you like
