Making Chicken Roll Ups is a simple process. Follow these steps for delicious results:

1. Preheat the Oven: Preheat your oven to 375°F (190°C) and grease a baking dish.
2. Prepare the Filling: In a bowl, combine the cream cheese, mozzarella cheese, spinach, sun-dried tomatoes, garlic powder, salt, and pepper. Mix until well combined.
3. Slice the Chicken: Take each chicken breast and slice it in half horizontally to create thinner pieces.
4. Fill the Chicken: Place a generous spoonful of the cheese mixture onto each chicken piece. Spread it evenly, leaving a bit of space around the edges.
5. Roll the Chicken: Carefully roll up each chicken piece, starting from one end and tucking in the sides as you go. Secure with toothpicks if necessary.
6. Place in Baking Dish: Arrange the rolled chicken in the prepared baking dish, seam side down.
7. Bake: Bake in the preheated oven for 20-25 minutes, or until the chicken is cooked through and no longer pink in the center.
8. Cool and Serve: Allow the roll ups to cool for a few minutes before removing toothpicks and slicing them into bite-sized pieces.
