What is a good metaphor comparing potato chips to love?

Yes, I know this a weird question but I’m writing a metaphorical poem comparing love to a potato chip.. For example, An onion is a moon wrapped in brown paper.. You know, because the moon represents romance, etc. I don’t know.. I understand this question is quite random and stupid but please help me out. I’m trying to make my own version of this with something other than an onion:

I’m not going to publish this poem anywhere so it’s not copyrighting or anything like that. Thanks again for any help you can give.
