Notes
*If the red onion smells strong or if you’re worried about being overpowered by it, slice the onion and then add it to a bowl of ice water. Allow the onion slices to soak for 5 minutes and then add them to the salad. This will cut the stronger flavors of the onion. Storage - save leftovers for up to 4 days in the refrigerator in an airtight container.
