Halloween Jack is a character in David Bowie's song "Diamond Dogs", which includes one of my favorite song lyrics of all time... "As they pulled you out of the oxygen tent, you asked for the latest party." This soup makes me think of Halloween Jack, as it's full of two kinds of Monterey Jack cheese, plus a little chili powder and tomato giving it a light pumpkiny color. And it's quick and warming, a good supper as you're trying to get your little goblins out of the door so they can get lots of candy on Halloween night.
