Oh gosh...there are so many variations of this delicious dish of meats, veggies, wine and bread crumbs on top. The classic, french version uses duck, but I've made some pretty tasty stuff using vegan foods, such as vegan sausage,or a combo of meat and non-meat ingredients. It's a little different, but it is still absolutely sumptuous. I would suggest that you look up the authentic, french version and go from there. BTW, it's better the next day.
