Mix the pork sausage, diced apples, cheese, and leeks together. Form 2 inch diameter meatballs and then flatten them into patties. Start these patties in a cast iron pan and brown them. After about 10 minutes, move your sausage patties into the oven and bake them for another 15 minutes. The sausages should come out golden brown.

Enjoy with a nice piece of bread, an egg, or a veggie.
