In culinary arts school, during garde manger class (cold food preparation), we learned that pickling has long been a means of food preservation. It actually dates back to over 4000 years ago.
Many different fruits, vegetables and other types of foods can be pickled. Other than pickles themselves, one of the most common pickled foods that’s now seen pretty regularly on menus everywhere is pickled onions.
Even if you’re not a fan of red onion (as I am not), you may really enjoy pickled red onions. The flavor changes during the pickling process to a sweeter, tangier taste due to the addition of a small amount of sugar and vinegar.

I made these pickled onions for a backyard cookout I was hosting. They were so easy to make and everyone was piling them on their burgers. I will definitely be making more to keep on hand at all times in the fridge.
