Preheat oven to 350 degrees.
In a large mixing bowl mash together bread and milk until a paste forms. If you need to use a little more milk that's fine.
Mix in the 2 eggs.
On top of the bread and egg mixture add the turkey, spinach, feta cheese, olives, diced tomatoes, garlic, oregano, salt, and pepper.
Using your hands, mix everything together until all the ingredients are evenly distributed. Try not to over mix.
On a baking sheet sprayed with cooking spray form meatloaf mixture into a loaf. Spread marinara sauce on top.
Bake for 1 hour 15 minutes.
Let the meatloaf cool for 5 minutes and serve.
