Combine first 5 ingredients (through green onion) in a large bowl.: The moment you mix the chopped chicken , diced apple , diced celery , dried cranberries, and chopped green onions you will notice a pleasing contrast of colors and textures, the pale chicken against the bright apple and deep cranberries. Use a large bowl so nothing gets compacted, and gently fold the pieces so they remain distinct. You should hear the tiny clicks of chopped celery and feel the resistance of firm apple as you stir, which indicates you have the right crunch. This step matters because mixing these base ingredients first ensures even distribution when the dressing is added, preventing sogginess. A common mistake is over mixing here which can bruise the apple and make the chicken fall apart, so be gentle and patient as you fold.
In a separate bowl, combine the mayonnaise and remaining ingredients, stirring well with a whisk.: As you whisk together the light mayonnaise , Greek nonfat yogurt , freshly squeezed lemon juice, salt, freshly ground black pepper, and ground cinnamon, notice how the dressing smooths and slightly thickens. The aroma of lemon and cinnamon will lift, and the whisk should leave faint trails in the dressing, showing it is emulsified. This technique helps the dressing cling to the salad components evenly, which is why I whisk until the texture is glossy. A pitfall here is adding too much lemon or salt at once, which can dominate the gentle flavors; taste as you go and adjust slowly.
Add the mayonnaise mixture to the chicken mixture, tossing well to coat.: When you pour the dressing over the mixed salad components, the first few gentle tosses will show how the dressing adheres, making the mixture look uniformly glossy. Use a folding motion with a large spoon or spatula so you don’t mash the apple or shred the chicken further. As you toss, watch for even coverage and listen for the quiet clinking of ingredients against the bowl, a small sign that everything is integrating. Let the salad rest for a few minutes so the flavors marry, and check seasoning before serving. One common trap is over dressing, which can drown the delicate textures, so start with the recommended amount and add a touch more if you feel it needs it.
