Pour 3/4 cup of cheese sauce onto the bottom of a baking dish that is 9×9 inches in diameter. Top 1/3 of the lasagna noodles with sauce, then top with 1/2 of the cooked chicken and 1/2 of the ham. Dollop 1 cup of sauce over the ham and chicken. Start with half of the remaining lasagna noodles, then add half of the remaining chicken, half of the remaining ham, and one more cup of cheese sauce. Repeat layering as needed. Lastly, add the remaining lasagna noodles, sauce, half a cup of Swiss cheese, bread crumbs, and Italian spice over the top. Place aluminum foil over the dish.
After approximately 25 minutes of baking in a preheated oven, the casserole should be bubbling. After 10 more minutes of baking without foil, the crumbs should be golden. Allow the dish to rest for 5 to 10 minutes before to consumption.
