Ingredients

1 jar pickled pepperoncini or any pickled vegetable
1 medium red onion peeled and sliced into thin circles

Instructions

Purchase a jar of any pickled veg (or use one you already have). I used pepperoncini this time but any pickled veggies will work.
Once the jar is empty of most or all solids, save the pickling liquid. Add the sliced onions to the jar and gently press the onions down with the back of a spoon, making sure the onions are fully submerged in the pickling liquid.
Put the lid back on and leave it in the fridge overnight. The following day you will be left with delicious pickled onions that you can use as the perfect topping to your favorite recipes. Enjoy!

Zest: Add lemon or lime zest to the pickling liquid for a citrusy twist.
Spicy kicks: For a spicy kick, add sliced jalapeños or other hot peppers to the pickled onions.
