Unlike the popular mayo-laden potato salad recipes, this one has a very savory and fresh taste thanks to the mustard vinaigrette. It is also naturally dairy-free, vegan and egg-free, so no need for substitutes! It is also a great backdrop for fresh herbs of the season. Consider adding fresh chopped dill or parsley just prior to serving.
This vegan potato salad is best eaten the day after it’s made, giving the flavors from the mustard vinaigrette time to intensify. When ready to serve, your can keep the potato salad cool by placing your serving dish in a larger bowl filled with ice.
