How To Make Pickled Onions

"This super quick recipe for pickled onions uses red onions (aka purple onions) and a simple brine with salt, vinegar, water, and sugar. You can have this from idea to table in about forty minutes. I love pickled anything: pickled beets, pickled carrots, and pickled onions. I wanted to make these pickled red onions because I was planning on publishing a recipe for rotisserie chicken tacos and pickled onions are bomb on them. Yes, I said bomb like the young kids. Pickled foods make you feel hip okay?"
