It's a spinach-and-cream-cheese dip, crammed into a hollowed-our round loaf of bread, then crammed in the oven and baked. The pieces of bread from the innards of the loaf are reserved for dipping into the goo.
It was literally of the first page of recipes for the book I chose. My wife loves spinach dip, and I can tolerate it, and I'm always looking for something more snack-like for weekend afternoons.
Now I just have to come up with a good bevvie to go along with it...
Ah - I understand now.
