Love pickled red onions on my salads, végé burgers and bowls as a topping
Combine apple cider vinegar in a bowl, you can sweeten with sugar and salt if you wish by simply adding to your pickling liquid. Whisk sugar & salt together until fully dissolved. Place sliced red onions in a Mason jar. Pour vinegar mixture over the red onions and let sit at room temperature for 1 hour.
*The reason I dont add sugar to the pickling is that the red onion already contains sugar and is sweet tasting
After 1 hour, store the pickled red onions in the refrigerator , keeps for up to 2 weeks.
