Creating Spinach and Feta Chicken Rolls is simple and can be broken down into these easy-to-follow steps:

1. Preheat the Oven: Start by preheating your oven to 375°F (190°C). Line a baking dish with parchment paper or lightly grease it.
2. Prepare the Filling: In a mixing bowl, combine the chopped spinach, feta cheese, cream cheese, minced garlic, oregano, salt, and pepper. Mix well until all ingredients are fully incorporated.
3. Prepare the Chicken: Place the chicken breasts on a clean cutting board. Butterfly each breast by slicing it horizontally, making sure not to cut all the way through.
4. Stuff the Chicken: Spoon a generous amount of the spinach and feta mixture into each butterflied chicken breast. Fold the chicken over to enclose the filling and secure it with toothpicks if necessary.
5. Coat the Chicken: In a shallow dish, place the breadcrumbs. Dip each stuffed chicken breast in olive oil, then roll it in the breadcrumbs until evenly coated.
6. Arrange in Baking Dish: Place the coated chicken rolls in your prepared baking dish. Drizzle with extra olive oil for added flavor and moisture.
7. Bake: Bake in the preheated oven for 25-30 minutes or until the chicken is cooked through and golden brown on top.
8. Check for Doneness: Ensure that the chicken reaches an internal temperature of 165°F (74°C).
9. Let Rest: Once cooked, remove the rolls from the oven and let them rest for about 5 minutes before slicing.
10. Slice and Serve: Slice the rolls for serving, presenting them beautifully on a platter.

These straightforward steps will guide you in creating delicious Spinach and Feta Chicken Rolls effortlessly.
