I was hoping no one would ask that as I'm not entirely sure, I just know it tastes nice, hehe!

Although heres a recipe which might given an idea: http://www.bbc.co.uk/food/recipes/breadsauce_84755

It looks a bit like porrige (argh I can't spell that!), in colour and texture, and you have it hot as a sauce over the meat, and its a mixture of bread, milk, onion, and some herbs. I think its mainly supposed to be eaten with turkey but we have it with chicken as well :)
