Prepare the dressing: Combine the shallot, lemon juice, vinegar and salt in a medium bowl and set aside for 5 to 10 minutes to soften the shallot.Add the olive oil in a steady stream, whisking constantly. Put the yogurt in a separate bowl and gradually add the vinaigrette , whisking constantly. (seems a little crazy to use to separate bowls to make the dressing, but the author explains that you need to add the thin liquids to the yogurt gradually to keep the dressing from breaking.) Dressing will keep, refrigerated in a covered container for up to 5 days.Reserve ¼ cup of the Lemon Yogurt Dressing and pour the rest into a big bowl to toss the entire salad.Cut the tops off the carrots and wash in cold water. Dry and tear into small tufts.Shave the carrots into long ribbons with a vegetable peeler. A u-shaped one works well. Add the carrot ribbons to the salad bowl with the dressing and toss, coating the carrots with the dressing. Just use your hands.Add the millet, raisins, seeds, parsley and carrot tops. Toss gently to combine.Crumbled the feta over the salad and toss again gently. Drizzle the reserved dressing over the top.
