Chicken Breast Stuffed with Spinach, Feta, and Pine Nuts

1. Preheat oven to 350ºF.
2. Wash and pat dry chicken. Using a sharp knife, cut a slit halfway through the chicken breast to create cavity for the stuffing.
3. Heat 1 tablespoon olive oil in a large ovenproof skillet over medium-high heat. Once oil is hot, add spinach and saute until wilted but still bright green, about 2-3 minutes. Remove from heat and roughly chop once cool.
4. In a bowl, mix spinach, pine nuts and feta. Add more pine nuts or feta to taste.
5. Sprinkle chicken breast all over with salt and pepper. Dust the outside of the chicken with flour. Stuff chicken cavity with spinach stuffing.
6. Heat the remaining tablespoon olive oil over medium high heat in same skillet. Cook chicken breast until browned on each side, about 3-4 minutes per side.
7. Place the skillet in the oven and cook until chicken breast is cooked through, about 20 minutes. Remove from the oven and let the chicken rest for 5 minutes before eating.
