Dream - Fruit cups.

Maybe not exactly the most healthy, and generates a fair amount of trash, but you have not lived until you're tired, cranky and hot AF and someone hands you an ice cold fruit cup. Pro Tip: to keep these cool, put ice you get from Arctica in ziploc bags so when it melts you (a) can drink the water (b) there is no soupy, stinky mess in your cooler as the days go by.
