From Huang Tingjian's Song-dynasty 《四休导士诗序》: 粗茶淡饭饱即休 ('plain tea and simple food - once full, stop'). Part of a recipe for a contented life: eat simply, wear warmly, don't covet, don't envy.

Often invoked positively - linked to the Confucian/Daoist virtue of contentment with little (知足). Not poverty so much as voluntary simplicity.
