Preheat oven to 350°F (175°C). In a large bowl, mix ground turkey, egg, salt and spices.
On foil, pat mixture to a rectangle. Gently press into meat. Top with cheese, ham, spinach. Optional, add a hard-boiled egg. Starting at short end, roll up tightly, using foil to start the roll and tucking in spinach leaves; seal ends.
Place into the baking dish.
Bake 1 hour. Optionally, spread ketchup over the top. Bake 15 minutes longer or until thermometer inserted in meatloaf reads 160°F (70°C).
Let stand 5 to 10 minutes before serving. Enjoy your meal!!!
