Notes
Expert Tips:
If you find the raw onion flavor too strong, soak the red onions in cold water for 20 minutes before using them to reduce the intensity. Then, drain the onions, pat them dry, and continue preparing the salad.
Refrigerate the salad for 30 minutes to let the flavors combine before serving them.
