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