Here's one I make all the time-- a good standby when you can't think of anything else.
Fettucine Alfredo
1 tablespoon butter
2 garlic cloves, minced
1 tablespoon all-purpose flour
1 1/3 cups 1% low-fat milk
1 1/4 cups grated fresh Parmesan cheese, divided
2 tablespoons lowfat cream cheese
1/2 teaspoon salt
4 cups hot cooked fettuccine (8 ounces uncooked pasta)
2 teaspoons chopped fresh flat-leaf parsley
Cracked black pepper
Melt butter in a medium saucepan over medium heat. Add garlic; cook 1 minute, stirring frequently. Stir in flour. Gradually add milk, stirring with a whisk. Cook 6 minutes or until mixture thickens, stirring constantly. Add 1 cup Parmesan, cream cheese, and salt, stirring with a whisk until cheeses melt. Toss sauce with hot pasta. Sprinkle with remaining 1/4 cup Parmigiano-Reggiano cheese and chopped parsley. Salt and pepper to taste
Serves 4, supposedly, but I'd double it to REALLY serve four.
