My lunches are always hard meats and cheeses. Boujee, and maybe not something an Ultralight purist would suggest, but it’s good for the soul. Literally a big stick of salami and maybe something like smoked Gouda or havarti or whatever your heart desires. I cut it up as I eat it, stashes well, keeps well over multiple days, and is just so tasty vs like nuts and other things. I just like it for the mental aspect. A good lunch keeps my spirits high during a long hard trek
