mucho pan para tanto salame
(too much bread for that salami) •
It's used when a person (usually a boy) isn't thought to deserve their partner. This can be either because of their appearence or behaviour. You can also say this to someone who's just broken up with their partner, meaning something like "don't be sad, they don't deserve you".
"María me dijo que fue a la casa del novio y que en vez de estar con ella, estuvo toda la noche jugando jueguitos. Ella es mucho pan para tanto salame."
"María told me she went to her boyfriend's house and instead of being with her, he spent the whole night playing videogames. She's too much bread for that salami."
