Preheat oven to 400 F. Line a medium sized casserole dish (9×13) with two pie dough disks. Trim and crimp edges.
Heat a medium cast iron skillet with olive oil on medium heat. Add in turkey sausage and cook for 8-10 minutes, stirring frequently, until cooked through. Add in kale and stir together with sausage. Add in 2-3 tablespoons of water and place a lid on pan for 2 minutes. Kale will steam and wilt. Stir together once more and remove from heat.
In a large bowls whisk together eggs, half and half, salt, and pepper. Gently stir in kale and sausage mixture. Pour egg mixture into prepared dough-lined casserole dish. Dollop egg mixture evenly with ricotta cheese.
Bake quiche for 45 minutes. Remove from oven and top with parmesan cheese, and return quiche to oven. Bake for an additional 10-15 minutes or until the top is golden brown and the middle of the quiche has just set. Cool for ten minutes before slicing and serving.
