What I would want in my imaginary diva trailer:

Double Stuf Oreos, Milano cookies, Teddy Grahams, Nutella, Skippy Peanut Butter, Reduced Fat Wheat Thins, Hummous, blueberries, granny smith apples, carrots, cherry tomatoes, bananas, and assorted teas and fruit juices.

Most of those are snacks but being a diva I'm sure I'd have a trainer to whip me into shape all the time.

Sushi-grade nori wrapped tuna (fresh, no rice) with soy sauce, chopsticks, and wasabi
Shrimp Cocktails like it's going out of style
Gevalia coffee
Hot hot chicken vegetable soup
oh, and fro-yo

Cranberry and/or orange juice
Wotsits(British equivalent of Cheetos)
Peanut M&M's
Vegetable Lasagne
Haagen Daas Baileys Ice cream.
If I went all out diva style, I'd consider requesting scented candles, no harsh lighting, fresh white roses and lilies, a masseuse and slightly chilled, filtered water. Can't you tell I've thought about this before.

Fitty has it right: KFC extra-spicy, Mac n' cheese from Boston Market...washed down with Cristal. Makes me want to be his groupie!

How long are these people backstage that they need so much food?
