Preheat oven to 400 degrees.

Grease a large baking dish or cookie sheet, I used an 11X15 baking dish, set aside.

Cook chicken in batches on the stove. I seasoned the chicken pieces with McCormick Montreal Chicken seasoning. You could use a combination of salt, pepper, and garlic powder.

While the chicken is cooking, pat all the moisture off the pineapple pieces to get them as dry as possible. This will prevent watery chicken. *I grilled the pineapple slices on my grill pan on the stove. I like the flavor and how it draws out the moisture.

Lay cooked chicken pieces in the baking dish, then layer diced ham over all the chicken.

Now layer the pineapple on top of the ham, and the cheese over the pineapple.

Place casserole dish in the oven for 5-10 minutes, or until cheese melts.
