Preheat oven to 450°.
Roll bread dough into a 12-inch circle on a floured surface. Place the dough on a 12-inch pizza pan or baking sheet coated with cooking spray. Crimp edges of dough with fingers to form a rim. Set aside.
Cook ground turkey in a nonstick skillet over medium-high heat until browned, and stir to crumble. Stir in 1 1/2 tablespoons taco seasoning, and reserve remaining seasoning for another use. Spread the turkey mixture over dough, leaving a 1-inch border. Spread salsa over turkey mixture, and sprinkle with olives and cheese. Bake at 450° for 20 minutes or until cheese melts. Top with lettuce. Let stand 5 minutes. Top each slice with sour cream.
