Good question...So many to pick from....
I haven't been in NA for over a year so I hope that all my choices are still being shown on the Food Network...If not please fogive an Irish bound Canadian lass
My favs are...
David Rocco (Such a cutie! - Oh and a really good Italian chef!)
Anthony Bourdain (Love him to pieces!!!)
Alton Brown (He's like that quirky, smart best guy frined you had in high school)
Nigela Lawson (If only for the fact that like myself, she isn't a skinny-minny but appears to have no qualms about it!)
I'm not sure if he's ever been on the Food Network but I just love Gordon Ramsey too! I trust any recipe that he makes or writes - I've cooked several of his dishes and they turn out like you're at a 5 star restaurant
