The best thing about making these quick pickled red onions is that it literally only requires a few ingredients, you can make them in minutes, and they only require one hour of refrigeration before you can eat them! They usually taste best if used within the first week or two of making them, but I promise they won't last that long! We use them in my Brisket Tacos, Chicken Taco Bowls and Shredded Chicken Tacos weekly.
