provecho
/pɾoˈbet͡ʃo/ · B2 · noun · m
benefit
🍽️ sounds like pro-vecho: a pro move that gives you benefit; buen provecho!
From Latin proficere, 'to make progress, be of use' (also source of English profit). Eating well is to your benefit, so buen provecho wishes the eater a good, beneficial meal. Think pro-fit: what makes you fit and gains you something.
