In the bowl of a food processor or in a blender, blend together a garlic clove, a pinch of salt, black pepper, greek yogurt, chopped mint, and lemon juice, and blend until smooth. If you want the lemon flavor to stand out more, feel free to add lemon zest as well. Pour the sauce into a small bowl, serve over honey harissa chicken, and anything else you like; it tastes so good! Use within 4-5 days.
