Add the baking powder, corn starch, egg, and mix well. Put the mixture in a food processor and pulse until smooth but a still a little chunky, about 15-20 seconds
Pre-heat a waffle iron and spray with non-stick. Add the mixture to the iron and cook for 7-8 minutes. If the waffles are not crispy enough, cook another 2 minutes.
Meanwhile, make the sauce by combining the greek yogurt and the rest of the ingredients, mix well and check for seasoning. To make the sauce have a “syrup” like consistency, add 1-2 tablespoons of water. Garnish the waffle with the sauce and chopped mint or parsley.
