Cook the Fettuccine: Boil a pot of salted water and cook the fettuccine pasta according to package instructions. Drain and set aside.

Prepare the Chicken: In a skillet, heat olive oil over medium heat. Add minced garlic and sauté until fragrant. Add the grilled chicken strips and pour teriyaki sauce over them. Cook until the chicken is heated through and coated in teriyaki sauce. Set aside.

Steam the Broccoli: Steam or blanch the broccoli florets until they are tender yet still vibrant green. Set aside.

Make the Alfredo Sauce: In the same skillet, pour in the Alfredo sauce and heat it gently. Stir in grated Parmesan cheese until the sauce is creamy and smooth.

Combine Ingredients: Add the cooked fettuccine to the Alfredo sauce, tossing to coat the pasta evenly. Then, mix in the teriyaki-coated chicken strips and steamed broccoli. Ensure everything is well combined.

Season: Season with salt and pepper to taste. If you like a bit of heat, sprinkle red pepper flakes over the dish.

Serve: Dish out the Teriyaki Chicken Alfredo onto plates, garnish with additional Parmesan if desired, and enjoy your delightful fusion of Italian and Asian flavors!
