This recipe is one of my favorite pasta bakes. It is simple to make and the presentation is fantastic. A perfect, hearty meal that can be served as a one dish meal. I prefer to serve this with hot, garlic bread. You can vary this recipe by using plain fettucine or adding chopped fresh herbs such as basil, parsley, or thyme. Grated carrot can be used as well. If you like garlic, stir in a crushed clove or two just before the onion is finished cooking. Voila!
