Dinner - Shrimp Fettucine Alfredo (lighter version)

A lower calorie version of Shrimp Fettucine Alfredo:
(approximate measurements) Serves 2
Ingredients
2 cups cooked fettucine
1/2 pkg fresh spinach
4 T fat free cream cheese
12 med. shrimp
1/2 cup shredded parmesan cheese
1/4 cup margarine
1/3 cup any fat free milk (low calorie dairy, soy, almond)
garlic powder/garlic salt/salt/pepper to taste
Directions:
Cook pasta as per directions.
Melt margarine and cream cheese in skillet.  Turn to low and add shrimp.  Cook about 3 min. then slowly add in milk, stirring to blend.  Add as much milk as needed, but not too much to make it too runny.  Add in parmesan and heat/stir till melted.  Add in spinach and cook for a couple minutes till wilted.  Mix this in a bowl with the pasta and divide onto plates.  I served with garlic toast.
This pasta recipe was approx. 575 calories per serving and the garlic toast was 140 each.
The fat free cream cheese makes this taste rich and I don't miss the calories at all.  Delicious!
