Keep some extra mustard and applesauce ready, depending on the saltiness of the cheese you use you might want to add some more. I buy the ready-made applesauce. If I do use fresh sage I like to use the pineapple sage that I grow in my garden. This is a simple but elegant dish and easy to double for dinner parties. It is from the Good Food magazine, I just changed it a bit to make it easier to put together.
