Blue cheese in a chicken salad? Well, why not! This tasty combination of flavors makes a delicious salad.
Combine the chicken, cheese, and walnuts in a bowl. In a smaller bowl, combine the oil, vinegar, garlic, shallots, salt, and pepper. Whisk until well combined. Pour over the chicken and toss to mix. Arrange the lettuce on a platter. Mound the salad on top. Garnish with the avocados, red onion, and oranges.
