Pickled red onions are one of my favorite ways to add a pop of flavor to just about anything—tacos, grain bowls, salads, sandwiches. They’re tangy, crisp, and take just a few minutes to prep.
Thinly slice a red onion. Add 1/3 cup vinegar + 2/3 cup water, 1 tsp salt, a dash of pepper, and a pinch of sugar. Let it chill in the fridge for 30 minutes and you’re good to go!
