I wish I could access the SF Chronicle's (or maybe the Examiners?) archives.
About five or six years ago, when I was pulling a copydesk shift for my paper's food section, I read a wire review of the best frozen pizzas available in nationalwide grocery stores.
Believe it or not, Safeway Select came on top or second from the top. I was a bit surprised, but when I later compared SS side-by-side with DiGiorno and Freschetta (the two I would even stoop to buying in desperation), I had to admit it was really tastier.
Agreed that the Trader Joe's is pretty darn good. Still, nothing beats a pie straight from a wood- or coal-fired brick oven.
