Feel free to get creative! Try different cheeses, mushrooms, or add-ins like sun-dried tomatoes, spinach, or caramelized onions. A pinch of red pepper flakes adds a nice kick! Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven. You can also bake this instead of pan-frying. Place the stuffed chicken breasts in a baking dish, pour the chicken broth over them, and bake at 375°F (190°C) for 20-25 minutes, or until cooked through. Substitute chicken broth with white wine, vegetable broth, or water.
