Cooking is a pain, cleaning up is a pain. For what? A pile of half-assed minute rice or some cruddy $20 MountainHome rehydrated spice mix?
Before leaving, smoke some meat overnight or buy tuna/chicken, bake some bannock, and carry some slow-rot produce like taters and apples along, with trailmix and all the gas station candy everyone brings.
Make a fire, wrap tater in tinfoil, chuck in coals for a bit, eat with meat/tuna and bannock. Literally done, no clean-up, just put foil in your trashbag.
Save like 2lbs and $100 worth of needless gear. Costs nothing. All the work is done at home.
