According to the package directions, cook the pasta to make chicken spaghetti with leftovers. Place the cooked noodles in an airtight container to keep them fresh. Wrap in plastic wrap or aluminum foil to keep warm. The prepared dish can be frozen for up to 3 months. Thaw it overnight in the refrigerator when you need a quick meal. Bake the dish for 15 minutes in the oven to reheat it from frozen. Use a microwave or an oven to reheat the chicken spaghetti.
Add diced peppers if you want them to be spicier.
