I'll be going on an 11-hour plane ride in a few weeks that offers no in-flight meals that aren't for purchase. I'll be damned if I spend $12 on a bad club sandwich, so I'll be packing 2-3 meals/snacks for the two of us.
Amanda has a whole chapter in Cooking for Mr Latte about what she likes to eat on planes, but sadly I don't think cheese and charcuterie will last the entire plane ride in my carryon. (Also I love the occasional Marcona almond, but I've never liked snacking on nuts as a way to get full.)
What are some sandwiches, dumplings, anything that are filling, easy to pack, store/age well, and aren't too messy to eat?
