Pie in a Bowl: Idea?

Today at the V&A cafe, I noticed they were serving a chicken pie in a bowl. I immediately noted this as a possible idea, as that would decrease cleanup by not using a pan! However, it is impractical for large numbers of guests as I only have four ceramic bowls (and how oven-safe is oven-safe anyway?)
Another idea would be to cook the pie in a bread bowl, like the soup-in-bread at Panera (and apparently at some exceedingly delicious place in Seattle, according to Anna P). I’d have to figure it out. Project!
