Anon, I got the following recipe many years ago from a Weight Watchers cookbook. I think it is very tasty.

Chicken Marsala
4 t Margaine (I use butter) (1 T plus 1 t)
10oz. Boneless, skinless chicken breast
1 T Minced shallots
1 c Sliced mushrooms
1/2 c Dry Marsala wine
1/4 c Instant chicken broth
1 t All-purpose flour
1/4 t Salt
Fresh ground pepper to taste

In 9 or 10 inch non-stick skillet heat margarine over medium heat until bubbly and hot; add chicken and cook, turning once, until browned on both sides. Remove to plate and keep warm. Add shallots and mushrooms and cook until softened; add wine and cook, stirring occasionally, until liquid becomes slightly syrupy, about 4 minutes. Replace chicken breasts and cook until heated through.
In measuring cup or small bowl combine broth and flour, stirring to dissolve flour; pour over chicken mixture and cook, stirring constantly, until sauce thickens. Sprinkle with salt and pepper and serve.
Serves 2

Enjoy
