You can either just stir all the ingredients together (in this case be sure to mince the mint leaves well)
OR place all the ingredients in a food processor and blend - you can blend a little or a lot depending on the texture you want in the end.
refrigerate and let the flavors develop together.
serve with pita bread triangles or on top of gyros
