1Heat oven to 400°F. In 1-quart saucepan, heat water and butter to boiling over medium-high heat. Remove from heat; stir in milk and potatoes until well blended (mixture will be thick).
2Insert 1 stick into each hot dog. Pack mashed potatoes around each hot dog, covering hot dogs completely. Roll in corn chips to coat; place on ungreased large cookie sheet.
3Bake 10 to 15 minutes or until hot dogs are hot and coating is light golden brown.
4Meanwhile, heat remaining tablespoon milk and Cheese Sauce in small microwavable bowl on high 30 to 40 seconds, stirring once. Serve loaded dogs with Cheese Sauce.
