Dehydrated pasta packs e.g. Knorrs are great, I've found the spicy tomato (arriabbata) was the tastiest despite thinking I'd prefer the creamy ones. Pinprick them, roll the air out, tape the hole up to save space. Though they weigh more grain pouches - from Uncle Bens rice (esp his Mexican rice) to Merchant Gourmet grains - are
bewilderingly delicious on the trail. You could have one or two of them and eat first before moving to the dry stuff. Get the right non-Chinese Asian noodles and you're in for a treat, the ones we get in Glasgow Asian supermarkets include freeze-dried shrimp and crab sticks in them,
they are A-One Brand. (The big tub needs "decanting" into a bag). Mini Babybel is a good way to take cheese with you, raw or tear it up into pastas or rice. Chorizo or salami is a good way to take protein with you that will last, taste great, replenish salt and fat, but also rend into food you're cooking. The UK store Morrisons does bite-sized mini chorizo from the deli and they're incredibly handy. Instant oats for brek and trail bars for lunch.
But this is by-the-by. You should be able to carry supplies if you get DEHYDRATED rations. There is enough water along the way.
PS, just to make everyone feel soft and fat and pampered beyond belief, think of Jim Taylor. In 2014 at the ripe young age of 91 he did his 20th TGO Challenge. Coast to coast. Solo. Wild-camping every night. His diet? He nibbled on oatcakes and drank water because he "can't be bothered with stoves and hot drinks".
Check out this
beautiful encounter and short video interview with him.
