hahah! Oh it's easy... say over breakfast-
her: "MMmm this is really good bacon"
you: "Hey while we're on the subject of pork.."
Seriously though, you can try to wait for the perfect situation to bring it up, but that may not come (no pun intended) anytime soon. If this is really something you want to bring up with her, think about arranging the opportunity yourself. Have drinks someplace quiet where you can talk (non-alcoholic ones A. because of your age, and B. the conversation will be more meaningful if you're both not completely smashed
), or go on a picnic in a scenic location, etc. If the right time is important to you, make that time happen. Just be clear you're not trying to pressure her, etc and I think you'll do fine.
