Selling out the sizzle

Got an email about a new work website today. The site itself looks fine, but the email describes it thus:

Essentially, the purpose of the site is to ‘sell the sizzle and not the sausage’

Is there anyone out there outside the marketing profession who actually thinks that selling the sizzle and not the sausage is a good thing? What planet to marketing people come from anyways? Maybe they're all annorexic or vegetarian or something...
