Wash all your greens and let drain. In the mean time in a small bowl add all the ingredients for the Vinaigrette and whisk. Once the greens have completely drained add into a bowl along with the Capers, Croutons, Feta if you wish, (others enjoy adding Feta into this salad and others don’t, it really is up to what you enjoy eating with your green salad), slowly drizzle the Lemon Vinaigrette and toss.
