In a large bowl, beat cream cheese until creamy. Then add sour cream, green chiles, olives, pepper jack cheese, salsa, and onion tops. Beat at medium speed with an electric mixer. Stir in spinach. Spread mixture evenly over the surface of each tortilla. Roll up tortillas tightly and cut each tortilla crosswise into 6 slices. Skewer each wrap with a wooden toothpick. Serve immediately or chill. Serve with salsa for dipping, if desired.
