Layer four 18-24" foil sheets on top of each other.
Cut 3 red potatoes into ½" slices and place on the foil.
Break asparagus slices and discard ends. Place on top of the potatoes.
Cut chicken breast into ½" slices and place on top of the potatoes and asparagus in a single layer. Season with salt and pepper.
Spread ¼ cup dressing on top of chicken.
Fold up the packet but just before sealing, add water. Seal tight, but not too tight, some steam can escape, usually on the ends is best.
Heat on a grill (about 350 degrees) for 30 minutes or until chicken is no longer pink in the center and potatoes are tender.
Serve as-is by tearing open the packet or transfer to a plate to serve.
Makes 1 packet and can serve 1-2 people depending on how big your appetite is.
