(Buddhist) monks just eat what they're given.

traditionally its not a large quantity. 

 I know a few monks and like Han Shan said they typically eat what they’re given (monastery monks). Monks or rather yogis  who take layperson life eat light and when hungry. Keep things simple. 

Unless you wanted Buddhist texts of the same idea 

 In the Dhammapada, the Buddha advises monks to eat in moderation, not for indulgence but to sustain the body.

	“Contentment is the highest wealth. The wise, by having understood this, do not delight in storing up things. They live in moderation, using only what is needed.” (Dhammapada, Verse 204) 

 I knowww but eating is so amazing 🥲 

 When you eat fully enjoy it. When not eating, fully enjoy life.
