One of my MOST favorite things is shiritake fettucini noodles. Just rinse well,then I cut them in half, since they are long. They are wonderful stir fried with just a little olive oil and an abundance of fresh vegetables! You can also saute some chicken breast or lean pork and have a great, healthy and very low calorie meal.
I am fortunate to have a shop nearby that carries these. If not, they can be ordered online.
