This refreshing salad is a great way to use up leftover rotisserie chicken. Simply shred the chicken and mix it with your favorite greens, such as spinach or arugula. Add some sliced cherry tomatoes, cucumber, and avocado for extra flavor and nutrition. Top it off with a simple vinaigrette made with olive oil, lemon juice, and Dijon mustard. This salad is perfect for a light lunch or dinner.
