  3. Preheat oven to 375F
  4. Heat a large cast iron skillet on medium and add fat and onions. Cook until caramelized—about 15 minutes. Add salt, spinach, and cheese. Stir until spinach is wilted and cheese has melted. Squeeze a splash of lemon juice along with fresh ground pepper and set aside.

  6. In another skillet, add fat and leeks. Saute until translucent and then add cumin, garlic, and salt. Stir to combine and remove from heat.
  7. In a large mixing bowl combine ground turkey, egg, spinach, and leek/spice mixture. Fold together until fully incorporated.
  8. Line a large baking tray with parchment paper and form turkey mixture into thin patties. Spoon a large serving of filling on top of each patty and top with another thin turkey patty. Pinch the sides of the two patties together to prevent the filling from oozing out.
  9. Bake for 30 minutes or until done.
