Preheat your oven to 375°F (190°C).
In a mixing bowl, blend the shredded chicken with mozzarella, cream cheese, sour cream, minced garlic, garlic powder, onion powder, salt, and pepper until thoroughly mixed.
Spread the flour tortillas on a flat surface and evenly spoon the chicken mixture onto each one, leaving a small border around the edges.
Layer fresh spinach and diced tomatoes on top of the chicken filling, and sprinkle fresh parsley if desired.
Carefully roll each tortilla, tucking in the sides to secure the filling.
Arrange the wraps seam-side down on a baking tray lined with parchment paper and lightly brush the tops with olive oil.
Bake for 15-20 minutes, or until the wraps are crispy and golden brown.
Allow to cool slightly before slicing in half and enjoy warm.
