Toss cubed chicken with 1/4 cup of Greek dressing and set aside.
In a medium size skillet, heat olive oil over medium heat. Add meat and cook, stirring frequently, until heated through. Remove from heat and allow to cool slightly.
In a mixing bowl, toss together the chicken, carrots, olives, artichoke hearts, and feta.
In a separate bowl, toss salad mix with additional 1/4 cup dressing, to taste.
Pile lettuce into serving bowls and top with chicken/vegetable mix and serve.
