In a large mixing bowl, combine cooked chicken, mozzarella cheese, cream cheese, and mayonnaise. Add minced garlic, Italian seasoning, salt, and black pepper. Mix until creamy and well combined.

Lay out flour tortillas. Spoon a generous portion of the chicken mixture onto the center of each tortilla.

Top each tortilla with fresh spinach leaves, diced tomatoes, and sliced green onions. Arrange toppings evenly.

Fold the sides of each tortilla inward and roll tightly from the bottom up to form a wrap.

Heat a skillet over medium heat. Add wraps seam-side down and cook for about 2-3 minutes until golden brown. Flip and cook the other side for 2-3 minutes.

Remove wraps from the skillet and let cool slightly before slicing in half. Serve warm.
