This dish, made as directed, has more than enough sauce to coat the pasta, so if you like to have plenty of protein at each meal, adding shrimp or extra-lean grilled chicken is a great option. For another 100 calories, you can add 3 1/2 ounces of grilled shrimp or extra-lean grilled chicken. And if you want to make the dish even leaner, omit a little bit of the butter.
