This simple salad is a great change of pace from a traditional greens salad, and it pairs wonderfully with chicken or fish. The shaved fennel and onions give it crunch, and it's livened up by a bright lemon vinaigrette. It can also double as a slaw; try it atop a pulled pork sandwich.
Note: Feel free to experiment with other additions, like cured olives or Mandarin oranges. If sherry vinegar is unavailable, red-wine vinegar will also work.
Combine all of the ingredients in a small mixing bowl and whisk until blended.
With a mandoline set on the thinnest setting, slice the fennel and onion into a large bowl. Add the parsley and fennel fronds, and mix until well combined. Add the dressing, and mix until combined.
