For the Pickled Onions:

• First, cut up your onion into thin slices and add them into a heat-safe jar with a lid. I really like mason jars for this.
• Next, we will start on our vinegar. In a small saucepan, add the vinegar, chili pepper flakes, honey, and salt. Bring the mixture to a boil. Once it's boiled and the honey is dissolved (might require some stirring), remove it from the heat.
• Pour the vinegar mixture into the jar, ensuring the onions are completely covered.
• Allow to cool for a minimum of 30 minutes, then enjoy!
