Butterfly the turkey breast. Pat the turkey breast dry with paper towels. Slice it horizontally, then pound it to an even thickness.
In a bowl, combine the cream cheese, olives, spinach, garlic, rosemary, thyme, salt, and pepper.
Spread the filling evenly over the turkey breast, then roll it tightly from one end to the other.
Brush the outside with melted butter, then season with paprika, onion powder, garlic powder, salt, and pepper.
Secure the roll with kitchen twine. Place seam side down on the baking tray. Bake for 30–35 minutes, then broil for the final 2–3 minutes.
Let the turkey rest for 10 minutes. Remove the kitchen twine, slice, and serve warm.
