The best thing about this salad is the dressing, and it needs salt. We're not big arugula fans, but we know arugula is good for us, and the dressing made it palatable. However, the dressing didn't penetrate the potatoes; they were bland. As for the sausage, we chewed and chewed and chewed its casing. It was like gnawing on plastic. If i make this salad again, I'll try using breakfast sausages without casing--and a pinch of salt in the dressing.
