Those monks know their stuff! The sherry makes this wonderful - don't leave it out! I like this best with Parmesan on top, but cheddar is awfully good too. Serve with crusty bread for a hearty, meatless meal.
Ideal for part of a supper or luncheon, these puff pastry shells, topped with chicken cubes and mushrooms in a creamy white sauce, are a classic entree.
