Vegie, Halumi, beef etc burgers were rather good from this outfit.  Om Noms, Nat Folk Festival Canberra. There are degrees of a good diet at a festival if you pick and choose, what would you make of the stockman's camp who did a spit roast whole lamb over an open fire plus big boilers full of potato pumpkin and greens, miles of onion gravy  and  damper with cocky's joy and billy tea for $12 in a smoky atmosphere with bush ballads. The 'chefs' were scrawny stockmen characters each wearing an old kilt skirt, thongs and maybe an old singlet and a broad brimmed hat.
