Add the 2 Tbs ghee to a large skillet. Once melted, add the diced onion with a pinch of salt. Heat on low until the onions are nicely caramelized, stirring occasionally, about 30 minutes.

Place the caramelized onions in a bowl and set aside (or in the refrigerator) to cool completely.

Once the onions are cooled, add all ingredients to a bowl and mix until well combined. Taste and adjust seasonings if desired.

Refrigerate for 1 hour.

Serve chilled with homemade potato chips or sliced vegetables.
