In a mixing bowl, mash 0.5 Avocado until really smooth, then add 60 g 0% Fat Free Greek yogurt, juice and zest of 1 Lemon, 2 Garlic cloves, 1 tablespoon Apple cider vinegar, 3 g Fresh dill, 1 pinch Sea salt and 1 pinch Ground black pepper.
Mix well until fully combined. You could blend to get a really smooth consistency, but it isn't necessary.
Add 100 g Cooked chicken breast (shredded) and 0.5 Red onion (diced) to the sauce.
Mix well to fully coat the chicken and onion.
