Add the romaine lettuce, sliced apples, cheddar cheese, grape tomatoes, dried cranberries, and red onion to a large serving bowl.
Arrange the cooked sliced chicken over the salad ingredients.
In a small bowl, whisk together the olive oil, white balsamic vinegar, pure maple syrup, Dijon mustard, kosher salt, and black pepper until well blended.
Drizzle some of the dressing over the Chicken Apple Salad just before serving.
Gently toss to coat the ingredients, or leave the chicken arranged on top for presentation.
Serve immediately with the remaining maple balsamic dressing on the side.
