Another tip I recall from "The FBC Queen" is to use name brand freezer bags, I think Glad or Ziplock. I ate most of my meals on the PCT last year out of freezer bags, well over 100 dinners that way, with never a problem. Standard Ziplock brand quart freezer bags, using a cozy bought from Sarbar, and of course always with a spoon.
With a little effort you can get darn near every bit of food and liquid out of the freezer bag at the end of the meal. Then put any loose food packaging trash inside, roll or otherwise flatten it, and seal up the ziplock and it doesn't smell or cause any mess or anything.
It's not for everyone, but I bring neither bowl nor cup when backpacking and don't miss them; the FBC approach is a key to that, whether using a prepared-at-home meal, transferring Mountain House or the like to lighter packaging, or throwing together ingredients available on the spot (lipton, ramen, dried potatos, stove top, instant rice, whatever).
