Boil pasta, drain the water, stir in a can of chili or something similar and heat again. Season. Enjoy with bread.
I like to cook eleborate meals even on short trips, so I always carry a two-pot nesting set. The second pot doesn't take up any measurable space or add much weight at all.
BTW...Brooklyn rocks. Out local Philly club rides from New Hope to B. Heights every year.
