This hearty, flavorful casserole is a great way to enjoy that leftover turkey or use diced chicken for this recipe. A rotisserie chicken would be a great choice as well. The homemade biscuits are a snap to prepare, but feel free to use purchased frozen biscuits to top this casserole. Add a caesar salad, simple tossed green salad, or serve the casserole with sliced fresh tomatoes for a fabulous everyday family dinner.
