Wayfarers are the same as military rations so if you don’t like the menus commercially available have a look at the military 24 hour ration pack supplies.
They do need flavouring some times with a bit of tobasco sauce or similar and the 24 hour packs comes with mini bottles of that.
Overall for the purpose they server they’re not a bad choice.
I find the dehydrated stuff to be far worse to eat on the trail and there is always the hassle of having to measure the water out and losing that water from your drinking supply to make the meal meaning you need to carry even more.
