Combine turkey, 1/2 cup salsa, sour cream and chiles. Spoon turkey mixture into tortillas; roll up and place seam-side down in an ungreased 13"x9" baking dish.
Blend together soup and remaining salsa; pour over tortillas. Bake, uncovered, at 350° for 30 minutes. Sprinkle with cheese and bake 5 more minutes or until cheese is melted. Top with shredded lettuce and chopped tomatoes, if desired.
