I think Beef jerky is your number 1 on this one. Its small for packing and light to carry as well. Other stuff you can dry are fruits, which is pretty great hiking food as well.
Moreover i always take some Uncured (thanks for the comment) bacon with me on a hike, goes great with just about anything you can cook and its also tasty if youre not frying it.
U can always go for veggies for the start of your trip. Though they wont make it the whole 10 days (most wont at least) you'll prolly keep them eatable for about the first 3 days. Think of tomatoes/paprikas for easy packing/hand snacks.
Last but not least, I love canned tuna on a hike. zip in 6 of these and you will have a buckload of proteins and fat along the way.
Like this question and im curious which answers it will produce (Serious Backpacker myself :) )
