In a medium mixing bowl, combine Greek yogurt, mayonnaise, and homemade onion soup mix. Stir to combine.
Cover and place in the fridge for 1-2 hours prior to serving. Top with chopped caramelized onions (see note), if desired. Makes 1 1/2 cups.
Serve with potato chips, vegetables, or anything you'd like! It makes a delicious sandwich spread, too.
Serving size: 2 tablespoons.
I like to use 2% Greek yogurt in this recipe. Full-fat and fat free will also work. If you choose fat free, it might separate and have a thinner consistency than if you use full-fat. Just give it a stir before serving!
