01 - Preheat oven to 375°F (190°C). Line a baking dish with parchment paper or lightly grease the surface.
02 - Heat 1 tablespoon olive oil in a skillet over medium heat. Sauté garlic and spinach until spinach is wilted, about 2 minutes. Remove from heat.
03 - Combine sautéed spinach, cream cheese, feta cheese, and cranberries in a mixing bowl. Season with 1/4 teaspoon salt and 1/4 teaspoon black pepper. Mix until evenly blended.
04 - With a sharp knife, make a deep pocket in the thickest side of each chicken breast, ensuring not to slice all the way through.
05 - Spoon the prepared filling evenly into each chicken pocket. Secure openings with toothpicks if necessary.
06 - In a small bowl, combine paprika, thyme, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Brush chicken breasts with 1 tablespoon olive oil and sprinkle seasoning blend over all sides.
07 - Place stuffed chicken breasts in the prepared baking dish. Bake for 25 to 30 minutes or until the chicken reaches an internal temperature of 165°F (74°C) and juices run clear.
08 - Remove toothpicks and allow chicken to rest for 5 minutes before serving.
