In what will be the greatest cooking demonstration in the history of time and space, Sonja Morgan, part of the Real Housewives of New York gaggle, will make an appearance at Macy's on Thursday night to promote her new toaster oven cookbook. Yes, you read that right. The single greatest member of an increasingly depressing and ill-mannered cast (e.g., Jill Zarin and that terrible lady who made millions shaving vaginas) will be in the city this week to sign copies of her latest book about cooking for royalty (et al.) using a toaster oven. Really, a goddamn toaster oven. This is what, among so many other qualities, makes Morgan a budding lifestyle genius.

Thursday's appearance is all a part of this year's Fashion Night Out. In addition to Morgan's appearance, Cirque du Soleil characters will run around the department store in full costume, Vince Camuto’s new line of attire will be on display along with free food and food (note: booze and credit cards are a terrible mix), and local blogger Blair Eadie from atlantic-pacific.blogspot.com will "style an informal modeling presentation filled with her of-the-moment looks and unexpected details, then share tips and tricks on how to create fashionable head-to-toe looks."

But you should go for Sonja alone. She arrives at 7 pm on the cellar level. To bide your time until then, please watch this helpful video on how she prepares Toaster Oven Chicken Parmigiano. (Gary Danko and Chris Cosentino, you both have much to learn form Ms. Morgan. Obviously.)
