Instructions

1. Step 1: Preheat oven to 375°F. In a bowl, mix together 2 cups chopped fresh spinach, 1/2 cup crumbled feta cheese, and 2 oz softened cream cheese until creamy and well combined.
2. Step 2: Using a sharp knife, create a pocket in each of the 4 chicken breasts (6 oz each) by slicing horizontally without cutting all the way through. Season chicken with 1 tsp salt, 1/2 tsp black pepper, and 1/2 tsp dried oregano.
3. Step 3: Stuff each chicken breast pocket evenly with the spinach-feta mixture, then secure with toothpicks if needed.
4. Step 4: Heat 2 tbsp olive oil in an oven-safe skillet over medium heat. Add the 4 stuffed chicken breasts and sear for 3-4 minutes per side until golden brown.
5. Step 5: Add 4 tbsp unsalted butter and 3 minced garlic cloves to the skillet, spooning the melted garlic butter over the chicken. Transfer skillet to the preheated oven and bake for 15 minutes until chicken is cooked through and juices run clear.
6. Step 6: Remove toothpicks, spoon remaining garlic butter sauce over the chicken, and serve immediately.
