A lot of weight can be saved by leaving the broccoli,apples and bananas at home. If you need that as a "morale" boost than it is different.
I don't get the idea of the umbrella for many reasons (I use trekking poles and often have scrub) but some like it, so whatever...
hard cheese is a good source of fat , protein and calories.
To hydrate your veggies (if that is the intention) you could use the wide mouth Nalgene Cantene. Lighter than the hard type.
Good warning about soap. I do use Bronner's but a tiny amounts (literally one drop or two) and well away from water sources.
Definitely look up Sarbar's site . I re-hydrate in the Caddy (that is my Caldera Cone storage container) but essentially practice the "boil in the bag" method.
Very fuel efficient and of course you don't scorch your food, (so I never wash my pot, just the container)
That also means you can happily fiddle with the night set up as the food "cooks"
