I didn't know it aired on Sunday till someone mentioned it, but a very good and evenly matched Iron Chef contest, Michael Symon v. April Bloomfield, airs again tonight at 11 pm on the food network and again on Saturday at 5 and 11 pm.  Most fun, for me, was the reunion with Andrew and Donatella.  Of course, since I'm judging, we already know who wins, but if you don't know Bloomfield, she's well worth paying attention to.
