I'm prepping for our trip, and to save money, time, and frustration with two young kids on the road, I'm packing sandwiches so we can eat whenever the mood strikes. (Or, more accurately, when both kids are finally passed out for just one motherfuck*ng minute seriously Pedro who died and made you king of driving the whole way you sit back here with these screaming children for just ten minutes and see how long it takes you to blow your top and can you just pass me a sandwich i don't care what kind no not that one and a soda too oh fuck it tunagiraffe is fine just pass it back quick before they wake up.)
Anyway, my question is, we're going to be on the road for three days, and some of the sandwiches will have lettuce on them. When I was a kid and my Mom did this, I never ate lettuce on my sandwiches, so I don't know how long it will keep in sandwich form. How far in advance can I make these sandwiches? I'd like to do them early next week, but some of them will be a week old by the time they get eaten, and I don't know if that's a good idea.
I'm taking mayo on the side, so bread sogginess shouldn't be an issue. I'm just worried about the lettuce getting all brown and wilty.
