Chopped green onions and sliced ripe olives, optional
In a small skillet, saute onion in butter until tender. Remove from the heat. Stir in the cream cheese, chilies and salt until blended.
In another skillet, cook tortillas in oil over medium heat until warmed and lightly browned on both sides. Drain on paper towels. Spoon a fourth of cream cheese mixture down center of each tortilla. Sprinkle with chicken. Roll up and place seam side down in an 8-in. square baking dish coated with cooking spray.
Bake, uncovered, at 350° for 15 minutes. Brush tops with milk; sprinkle with cheese. Bake 5-10 minutes longer or until cheese is melted. Sprinkle with green onions and olives if desired.
