Preheat oven to 425 degrees.
Using your hands, combine the turkey, sausage, celery, leeks, apples, salt, poultry seasoning, and pepper until well blended. Form into six patties.
Place the patties onto a lightly greased baking sheet (a little vegetable or olive oil will do the trick).
Cook for about 12 minutes, until fully cooked (internal temp of 165 degrees).
Place each cooked patty onto a potato bun. Top with warmed gravy and cranberry sauce.
