I would have to say most recently the recipe that I made (and have made many times before ) that was a hit was just simply Chicken Marsala. This isn't my EXACT recipe but it's close. I didn't feel like typing it out :)
4 ea Chicken half-breast, boneless & skinless
1/4 cup Flour
1/2 tsp Salt
Pepper to taste
1/2 tsp Oregano, dried
4 Tbsp Oil
4 Tbsp Butter (or margarine)
1 cup Fresh Mushrooms, sliced (or canned)
1/2 cup Marsala wine (chicken broth or cheap white wine also works)
Pound chicken breasts between sheets of "Saran Wrap" until about 1/4" even-thickness
Combine flour, salt, pepper and oregano, blend
Dredge chicken pieces in the flour, shake off excess
Heat oil and butter in frying pan over medium heat.
Cook the breasts on medium heat for about two minutes on the first side, until lightly brown
Turn breasts over to second side to cook, add the mushrooms around the chicken breasts
The only difference is that I take the chicken out after it is done and put it aside. Sautee mushrooms and then mix in a can of cream of mushroom soup, add chicken back in to the mixture and simmer for about 10min.
Cook breasts about two more minutes, until lightly browned on the second side, stir the mushrooms
When lightly browned, add Marsala around the chicken pieces, cover and simmer for about ten minutes
I always serve with a side of whole wheat pasta-usually spaghetti.
