  • Soak the sliced red onion in cold water for 10 minutes to mellow its bite.
  • Toss the salad with the dressing just before serving to keep the vegetables crisp.
  • Make the dressing up to a day ahead and store it refrigerated; whisk again before using.
  • Feel free to swap cilantro for mint or basil depending on what you have on hand.
