Feta and Spinach Stuffed Chicken

1. Preheat oven to 350 degrees F. 2. Saute the spinach in hot oil until wilted. Let cool. 3. Combine feta and cream cheese until evenly mixed. Mix in wilted spinach. 4. Cut a small slit lengthwise into each chicken breast. Gently using your fingers, create a pocket inside the chicken breast, being careful to not poke holes all the way through the meat. 5. Divide the spinach and cheese mixture into 4 and fill each breast with the mixture. 6. Put the stuffed breasts onto a baking sheet, at least 2" apart. 7. If desired, sprinkle a small amount of parmesan cheese on top of each breast. 8. Bake for 20-25 minutes or until chicken is cooked all the way through. Let cool on pan for 5 minutes before serving.
