You can make a quick shrimp alfredo using already made products. You can but the shrimp from your grocery store and prepare the shrimp to your liking. There are some great alfredo sauces already jarred in the pasta isle for you to use. Cook your fettuccine till its just about done. Warm up your sauce, and then toss everything together. You can add seasoning to taste. I usually will add brocolli for some extra veggies in mine.
