Looking at metaphors in Gurbani - often times when the poetic devices fly over the readers head they might take literally a metaphor translating it into an injunction
This is line uses ਰੂਪਕਾਤਿਸ਼ਯੋਕਤਿ - where the comparable in the metaphor is implied. Here the coarse roti, the vegetables without salt both represent a life without the desire/pull towards extravagance - simplicity.
Farid! My roṭī is coarse, my hunger, vegetables without salt.
Those who eat buttered roṭī will suffer great pain.
