Heat olive oil in a large pan over medium-high heat. When hot, add potatoes and reduce heat to medium. Cover and cook for about 20 minutes, stirring occasionally.

Set potatoes aside.

In the same pan, add sausage and brown about 10 minutes.

Stir in onions, parsley, and garlic. Reduce heat to medium-low and cook about 6-8 minutes.

Stir in zucchini and cook about 5 minutes.

Finally, add potatoes back into the pan and cook an additional 6-8 minutes.
