Saw this great graphic in the NY Times book review this weekend detailing the favorite writing snacks of a random assortment of famous writers. Including:
Walt Whitman: meat and oysters.
Emily Dickinson: Home baked bread.
John Steinbeck: Cold toast and stale coffee. On purpose?
My favorite writing snack is a little bowl of cheezits and peanuts. Sometimes it gets a little greasy but it always hits the spot. When I was little my favorite reading snack was a box of wheat thins. It seems like a natural evolution.
Your favorite writing, or other work, snack?
Ideas In Things 
i definitely have favorites – though the favorites seem to come and go with a few standbys always satisfying the need to snack when writing.
recent favorites: animal crackers — those ones you can buy in bulk (i think this is a result of hanging out with eliana for a few days) & pita chips (slightly obsessed)
old standbys: popcorn (the kind you make in a pot), cheezits, wheat thins, & gummy bears
