In a large mixing bowl, combine 2 tablespoons of olive oil, 2 tablespoons of lemon juice, 3 tablespoons of mayonnaise, 1 clove of minced garlic, ¼ teaspoon of salt, and ¼ teaspoon of black pepper. Whisk these ingredients together until they are fully blended and creamy.

Gently fold in 2 cups of shredded cooked chicken, ½ cup of chopped sun-dried tomatoes, ¼ cup of thinly sliced red onion, and 2 tablespoons of freshly chopped basil. Stir carefully to combine all the ingredients well.

Take 4 cups of mixed salad greens and place them on a large serving platter or divide them among individual plates.

Spoon the dressed chicken mixture generously over the bed of salad greens.

You can serve this salad immediately, or cover it with plastic wrap and chill in the refrigerator for 15 to 20 minutes.
