Ex. Always the gastronaut, Neil had packed plenty of his favorites for this mission; "Jane, can you hand me a packet of freeze dried cranberry duck confit and a couple rations of miso-dusted, roasted fingerling potatoes? Please don't add the lemon tarragon dressing to the string bean salad though - there was a clog in the toilet earlier and I'm wary of all floating, yellow droplets now."
