1. Preheat oven to 375 degrees Fahrenheit.
2. Stuff the center of the butterflied turkey breast with the spinach mixture. You will have the best results if you push the stuffing in from both ends. Place turkey in a roasting pan.
3. In a small bowl, combine olive oil, water, lemon juice, paprika, cumin, and pepper. Pour over turkey roast, turning the roast so that the marinade reaches all sides.
4. Sprinkle evenly with parsley flakes. Cover and bake for one and a half hours. Let cool before slicing.
