"Around My French Table" by Dorie Greenspan. Exciting French recipes gathered over the years by Dorie, not haute cuisine, but delicious comfort food you would serve your family and friends.
An easier version of the pie made with ground or minced beef is posted on the sidebar. I imagine it's just as good and less work.
