I like to add some sweet, juicy, fresh oranges or clementines to quinoa and then add some of the zest to dressing. If you can’t get fresh, juicy oranges, don’t bother. Canned mandarins don’t give the same burst of fresh flavor.
Refrigerate vinaigrette for about a week. Olive oil will solidify like melted butter solidifies.
Mix quinoa salad shortly before serving. Orange in dressing will stop apples from discoloring.
