Step 1

Place sliced onions into clean sterilized jars, pack tightly. (If I'm out of mason jars, I like to use old spaghetti sauce or pickle jars! Just make sure they're well cleaned.)

Step 2

Combine vinegar, water, sugar and salt in a microwave safe glass or bowl and microwave for 1 - 2 minutes, until salt and sugar dissolve when stirred.

Step 3

Pour brine over onions, cover and refrigerate at least two days. When the onions have turned an even shade of pinkish purple, they're ready.

Step 4

Enjoy!
