Easy Pickled Red Onions

This recipe is a fast, refrigerator type, pickle recipe. These red onions are delicious and keep for about a month in the refrigerator, if they last that long. This recipe fills a pint sized jar very full which is pretty amazing considering that it only costs $0.79 for the entire recipe. Pickled red onions are delicious on hot dogs, hamburgers, salads, sandwiches, wraps, tacos, and even on top of Asian inspired bowls.

We don't like things very salty in our house. If you love salt, you might want to increase the amount of salt in this recipe to one tablespoon.
You can add more garlic to the recipe if you choose.  I didn't have large garlic cloves and used three smaller ones.
