The size of your pie tin will determine the number of pies you can make. Try this recipe with small shrimp or crab for a tasty seafood variation. When refrigerated, the crawfish filling should be thick enough to form into a ball. Any extra crawfish filling makes the perfect stuffing for a breakfast omelette.

To reheat, I do not recommend the microwave; bake in the oven until heated through.
