Quick Pickled Red Onions
Optional flavorings:
  1. Combine vinegar, sugar, and salt in a small saucepan. Heat on low, stirring occasionally until salt and sugar dissolve.
  2. Add water. Let mixture cool.
  3. Add red onions to a jar along with optional flavorings. (I used a 1-liter size jar, which is a little over two pints.)
  4. Pour liquid into jar. Let sit at room temperature for one hour, then refrigerate.
  5. Onions will keep in fridge for two weeks.
