Good recipe for leftover chicken

About 2-3 times a month, I buy a rotisserie chicken from the
supermarket. After the meal, there is a lot of chicken left over. I
make sandwiches with it, but would like a little variety.

Can anyone suggest a good recipe to use the leftover chicken in? I am
thinking about a simple casserole or a sauce to pour over rice or
noodles.

My mom used to make a sauce with leftover chicken and either Cream of
Chicken of Cream of Mushroom soup or both. I think she added butter,
too. It was very good, but probably not so healthy.

Any similar, but healthier, alternatives?

Thanks
