Wharton 2013 - Calling All Applicants

Seems sensible. I do put a lot more into cooking that just basic sustenance (know you were just making a point ) -- I like to challenge myself and cook new and exciting dishes when I can (unfortunately, work and other commitments (MBA apps) don't afford me time to test 2 new recipes a week, but when I do get time I might spend a whole day in the kitchen), love classic French the best -- but, still, how do you work this into the Wharton hobbies section? They give you four entries to fill in: Club/organization, Positions held, Start date/end date, and # hrs per week. There is no room for explanation, other than 250 characters for all your hobbies combined to explain which activity you enjoy the most and why. Is it bad to just leave the hobbies/interests section blank entirely and depend only on the more formal ECs listed in the activities section? I would like to show some of my other interests outside of work to highlight a multifaceted personality, beyond what I will be writing in one of my essays (which conveys just one of my personal passions), but seems like this is the only place to do so (no room on my resume, and even if I did have room I frankly think it a little amateurish to list hobbies on a professional resume). Might just end up scrapping the whole section, though.
