It's easy to add chicken to your Fettuccine Alfredo. First, use a meat mallet to gently pound your boneless, skinless chicken breasts so they're an even thickness, then season well on both sides. Salt, pepper, garlic powder, and paprika, or a general seasoning salt would work well. Saute in olive oil until browned on both sides and cooked through. Slice into strips and arrange over a serving of the pasta. Sprinkle with some minced parsley to serve.
