1. In a Dutch oven, cook the beef over medium heat until no longer pink; drain. Stir in the taco seasoning and water. Bring to a boil. Reduce heat; simmer, uncovered, for 15 minutes. 2. In a large mixing bowl, beat the cream cheese, milk and dressing mixes until blended. Spread over two 14-inch plates. Layer with beef mixture, chilies, onions, lettuce, cheese and tomatoes. Drizzle with barbecue sauce. Arrange some tortilla chips around the edge; serve with remaining chips.
