Cadair was a slog!
In the hills, I usually carried a tin of sardines, packs of Supernoodles and a couple of choc bars as emergency rations in case I didn't get to any shops in time to get something more substantial
For lunches in the hills in the Lakes region, I took a pack of Krackerwheat, some of that tubed cheese stuff, and, yes Noggy, Mattessons sausage - slice the sausage (cold) onto the crackers, top with the squeezy-cheese and you're done. Packets of fresh (as opposed to dried) pasta ok too - I liked the cheese n ham-filled pasta shells myself. Boil in the bag meals are ok if you pick the good ones, but backpacking uses a lot of energy, and each meal was about a fiver - really needed at least two of an evening to replenish expended energy.
On a bike? Cafes and takeaways has to be the way to go!
