Rinse the Brussels sprouts. Cut off the ends and remove any damaged leaves. If you have a food processor, set it up with the slicer blade and enjoy the pure joy of dropping the sprouts down the shoot. If you don't have a food processor, thinly slice the sprouts (a sharp knife or mandolin works well). Once the Brussels sprouts are all sliced, give them a good bath in a salad spinner or large bowl to get all the trapped grit out. Spin or drain and pat them dry.
Combine all of the salad ingredients in a large bowl. Top with dressing and toss to coat.
Combine all of the dressing ingredients in a jar and shake to combine. Taste and adjust as necessary.
