I usually go cookless when I'm solo. My list looks pretty similar to yours, with a few additions. Powdered hummus is good nutritionally, and great with crackers. Instant mashed potatoes rehydrate easily with cold water. Mixed with a little Nido, they taste better. To make them really good, and add more protein, bring grated parmesan/romano cheese. Dried chives add a little color and flavor, and with some bits of jerky, they start to taste like something one might eat at home. Dehydrated refried black beans (Santa Fe Bean Company) are another good source of vegetable protein. They're slow to rehydrate in cold water, but do decently if you give them enough time. But I also like to munch them dry - they're like chips. And speaking of chips, crushed corn chips hit the spot on the trail (I prefer blue corn). Real vegetables are a little trickier. Lately, I've been bringing dried seaweed snacks that Trader Joe's has started selling. I like these enough that I eat them at home, and while they'll probably disintegrate a bit in your pack, it doesn't change the flavor.
My biggest challenge on long trips is keeping the calories/gram high, and that means good fat sources. Nuts, nuts and more nuts, and lots of Nido for after the string cheese runs out.
P.S. I haven't tried it yet, but I'm betting that kumquats would be a great way to bring some fresh fruit. Relatively low water content for a fruit, you eat the whole thing, lots of flavor and vitamins in a small package, pretty durable, at least for a day or two. Has anybody tried them for backpacking?
