Preheat oven to 400 degrees. Combine ground round, taco seasoning and green chiles in a bowl, mixing lightly but thoroughly. Divide beef mixture into 18 portions; shape each portion around a cheese cube, completely covering cheese. Beat egg white with water in a shallow dish until blended. Place chips in second shallow dish. Dip each meatball into egg white mixture, then into chips to coat completely. Press each meatball with palm into a flattened nugget shape, generously coating both sides with chips. Spray a large baking pan with non-stick spray. Place nuggets in baking pan; spray tops of nuggets with non-stick spray. Bake 15 - 20 minutes, until inside isn't pink and juices show no pink color. For sauce: Combine taco sauce and honey in small dish. Serve as dip with nuggets.
