Preheat the Oven to 400°F (200°C). Lightly grease a 9x13-inch baking dish with olive oil or spray.
Make the Filling: In a bowl, mix the ricotta, parmesan, garlic powder, salt, pepper, and steamed spinach until well combined.
Flatten the Chicken: Place each chicken breast between two sheets of plastic wrap. Pound with a meat mallet until about ¼ inch thick.
Stuff and Roll: Spread 2–3 tablespoons of filling onto each chicken breast. Roll tightly, starting from the short end.
Wrap with Prosciutto: Lay 3 slices of prosciutto on a board, slightly overlapping. Place the chicken roll seam-side down, then wrap the prosciutto tightly around it.
Bake: Place the wrapped chicken rolls in the prepared baking dish. Drizzle with olive oil. Bake for 25–30 minutes, or until the chicken is cooked through (165°F) and the prosciutto is crisp.
Garnish and Serve: Let the rolls rest 5 minutes before slicing. Top with chopped parsley and a squeeze of lemon juice, if desired.
This makes 4 servings. Each stuffed chicken breast is 10 WW Points. Enjoy!
