the snack stash for 3am hunger... what goes in it

last weekend we ate the entire contents of the hotel mini-fridge at half three after a long session and it cost us £47 which is mental for a snickers and two pringles tubes... lesson learned, we need a snack stash. so im polling — whats in your 3am bag. im thinking salty/sweet/easy/no smell. like crisps are good but they crinkle, choc bars melt if youve left them in the car, cheese is great but stinks the room out. whats your no-fail late night snack that travels well and doesnt cause a row...
