i have too many foods i like and would want to have one last time but it sounds nauseating to cram them all into one day. instead, i think the week before i ctb, i'd eat nothing but my favorite foods, regardless of price. what does money matter when you're dead, anyway? worst case scenario, we'd put it all on my fiancée's credit card. we have no next of kin to take on the debt, so we wouldn't be burdening anyone.
that said, my very last meal would probably be a bagel (either an egg bagel or an everything bagel, maybe one of each) with cream cheese, a fried egg, and cheddar. it's such a nostalgic and comforting meal to me that nothing else would be better than that. i think i'd want polar chocolate soda one last time alongside that.
(on a side note, sometime in that week, i'd want steak. i'm a vegetarian and have found non-meat alternatives that i like for everything but steak. i think i'd regret it a little if i didn't have steak and mashed potatoes one more time.)
