Creating the perfect Spinach & Feta Rolled Chicken requires following these straightforward steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Filling: In a mixing bowl, combine the chopped spinach, feta cheese, cream cheese, minced garlic, oregano, salt, and pepper. Mix until well blended.
3. Prepare the Chicken: Place a chicken breast between two sheets of plastic wrap. Using a meat mallet, gently pound the chicken to an even thickness, about ½ inch.
4. Fill the Chicken: Remove the plastic wrap and place a generous amount of the spinach and feta mixture onto each chicken breast.
5. Roll the Chicken: Carefully roll up the chicken tightly from one end to the other, ensuring the filling stays inside. Secure the ends with toothpicks or kitchen twine.
6. Sear the Rolls: In a large oven-safe skillet, heat a drizzle of olive oil over medium-high heat. Add the rolled chicken and sear for 3-4 minutes on each side until golden brown.
7. Bake: Transfer the skillet to the preheated oven and bake for 25-30 minutes or until the chicken is cooked through and the internal temperature reaches 165°F (75°C).
8. Rest: Once cooked, remove the skillet from the oven and let the chicken rest for 5 minutes.
9. Slice and Serve: Carefully remove the toothpicks or twine, and slice the rolled chicken into medallions for an elegant presentation.
