• Chicken Flavored Stuffing Mix – Use a 6-ounce box, prepared according to package directions. Also a great way to use holiday stuffing leftovers!
• Cream of Chicken Soup – Provides a creamy base for the casserole. Skip the can and make your own homemade cream of chicken soup if you prefer. 
• Dijon Mustard – Adds a subtle tang and depth of flavor.
• Cooked Chicken – Boneless, skinless chicken breasts, cooked and cubed. Rotisserie chicken or leftover chicken or turkey also work well.
• Ham – Diced into bite-size pieces. Leftover ham from the holidays is a great option, or use the pre-cubed ham or ask the deli counter to slice it thicker and cube it yourself. 
• Swiss Cheese – For that melty, cheesy goodness. I use sliced, but shredded works too!
