Spray 4 large sheets of aluminum foil with oil. Set aside.
Mix stuffing and water together in a mixing bowl. Spoon ¼ of the mixture onto each aluminum foil sheet and set a chicken breast on top of each. Top each one with ½ cup of broccoli. Sprinkle with ¼ cup cheese, ¼ of the bacon, and a drizzle of ranch dressing.
Fold the sides of the foil up into a packet.
Place all the packs onto a baking sheet and bake 20 - 25 minutes depending on the thickness of the chicken.
