Directions

1.    In a large skillet, heat half the oil over medium heat. Add the apples and the scallion whites. Cook, stirring occasionally, until the apples soften and just begin to brown, 5 to 8 minutes. Let cool for 10 minutes. 
2.    In a large bowl, combine the cooked apple mixture with the turkey, scallion greens, sage, fennel seeds, salt and pepper. Mix with your hands until well combined, being careful not to compact the mixture. Gently shape into 8 patties, about 3 inches in diameter and 3/4 inch thick.
3.    Heat the remaining oil over medium heat. Cook the patties, being careful not to crowd them, until browned and cooked through, about 5 minutes per side. You may need to cook in batches, add more oil and adjust the heat to prevent overbrowning. Keep the sausages warm on a baking sheet in 200 degree F oven, covered with foil.
