For a nuttier flavor, try toasting the pepitas in a dry skillet over medium heat, stirring constantly, until golden brown. If you don't have dried apple chips, substitute with diced fresh apple for a different texture and sweetness. Experiment with different cheeses, such as goat cheese or feta, for a unique twist. Make the vinaigrette ahead of time and store in the refrigerator for up to a week. Shake well before using. Adjust the amount of sugar in the dressing to your liking, depending on the sweetness of the apple chips and cranberries.
