I have been serving this rich and zippy chicken casserole for years, and it's a favorite of my family and friends. It disappears quickly at bring-a-dish gatherings, too. —Thom Britton, Three Rivers, Michigan
In a large bowl, combine the first 7 ingredients; mix well. Crush chips; set aside 1 cup for topping. Add remaining chips to chicken mixture. Spoon into a greased 13x9-in. baking dish; sprinkle with reserved chips. Bake, uncovered, at 350° until cheese is melted and edges are bubbly, about 30 minutes. Serve with sliced jalapenos and diced tomatoes if desired.
