Classic creamed pasta dish with a nice balance of flavor, color and nutrition. Like many Italian-style dishes, it's flexible as to ingredients. [Idea suggested by Corky Jackson Hintz].
Egg noodles. Medium, wide, and extra-wide are all good choices. Add drained noodles to the sauce while they're still slightly undercooked. Reserve some pasta cooking water to add to the sauce. NOTE: 12 oz of noodles is enough (ignore the 14-16 oz suggested under "Prepare pasta" below.
Chicken breasts. Cut breasts into thin strips (no more than about 1/8"). To make slicing easy, chill breasts in freezer for 15-20 minutes first. For added flavor, toss strips with a tablespoon of Worcestershire or soy sauce; put marinated chicken in refrigerator for an hour or so before cooking.
Cream cheese - sour cream - heavy cream. Use what you prefer. Both cream cheese and sour cream add a pleasant acidic taste.
