Place your chicken breasts or tenders along the bottom of the casserole dish.
Sprinkle with shredded Swiss cheese.
Distribute the Stovetop Stuffing over the Swiss cheese.
In a small bowl, whisk together the cream of chicken soup and water. Pour the mixture over the entire casserole - covering the stuffing completely.
Cover the casserole dish with tin foil and bake for 30 minutes.
Remove the tinfoil and check the internal temperature of the chicken with an inserted meat thermometer. If it hasn't reached 165 °F (74 °C), return the casserole dish to the oven and continue cooking for up to 10 more minutes or until chicken reaches temp.
Notes
Note: some families prepare the stuffing before assembling the casserole, but that's personal preference. I never have and I find that the stuffing is perfectly cooked and soft so I prefer to skip the extra step.
