Preheat your oven to 375°F (190°C).

In a skillet over medium heat, sauté the chopped spinach and minced garlic in olive oil until the spinach wilts. Remove from heat and let it cool for a few minutes.

In a bowl, combine the sautéed spinach and garlic with crumbled feta, dried oregano, dried thyme, salt, and pepper. Mix well to create a flavorful stuffing.

Lay the chicken breasts flat on a cutting board. Using a sharp knife, make a horizontal slit along the side of each chicken breast, creating a pocket without cutting all the way through.

Generously stuff each chicken breast with the spinach and feta mixture, ensuring an even distribution of the delicious filling.

Use toothpicks to secure the open sides of the chicken breasts, keeping the stuffing in place during cooking.

Season the outside of each stuffed chicken breast with additional salt, pepper, and a sprinkle of dried herbs if desired. Place the stuffed chicken breasts in a baking dish.

Bake in the preheated oven for 25-30 minutes or until the chicken is cooked through and the juices run clear.

Allow the stuffed chicken breasts to rest for a few minutes before removing the toothpicks. Slice and serve these delightful Spinach and Feta Stuffed Chicken Breasts as a savory and satisfying main course.
