Easy Pickled Onions

I've had pickled onions at several restaurants and always really liked them.   They add a certain pizzazz and "fancy" to a dish that I really like.   Well, it turns out they're really easy to make!   Here is the (super easy) recipe

I like these in potato salad, on a grilled cheese sandwich with some avocado, in quinoa... the possibilities are endless!

They take a burger to the next level, for sure =)
