In 10-inch skillet, cook beef until brown; drain.
Stir in sauce mix, uncooked rice and topping mix (from Hamburger Helper box), and milk and hot water. Heat to boiling.
Reduce heat. Cover; simmer about 20 minutes, stirring occasionally, until rice is tender.
Remove from heat. Spoon about 1/3 cup beef mixture into each of the chip bags. Top each with cheese, lettuce and salsa.
