Cranberry-Apple Tuna Salad is a refreshing and flavorful twist on the classic tuna salad. This salad combines tender chunks of tuna with sweet and tart cranberries, crisp apples, and crunchy celery. The addition of mayonnaise and Dijon mustard creates a creamy and tangy dressing that coats the ingredients perfectly. Serve this salad on a bed of lettuce, in a sandwich, or with crackers for a light and satisfying meal.
