Any thing with Bobby Flay since 9 out of 10 it's grilling. Paula Dean makes some great souther foods (read:very fattening but taste awesome). Iron Chef and Good eats are great shows as well.
My wife and I really got into Top Chef. I don't mind saying that I would probably never eat most of the food they cooked though. I would rather have a plate of Emeril's cooking than the "high society" food. The girl Casey on the past episode was fine.
