Red onions can sometimes be a bit abrasive and overpowering to the palette, but these 5-Minute Pickled Onions are another story. They add a bright, contrasting flavor to rich foods, like stews or braised meats. The are also delicious on top of pizza, tacos, or sandwiches. Part of pickled onions’ allure is their bright pink color. And you can make them in 5 minutes with ingredients you probably already have on hand.

Try topping Korean Beef Tacos with pickled onions. It adds a much-needed, bright flavor (and color!) contrast to the rich, unctuous beef.
