Can you recommend Jazz for some one that doesn't like Jazz?

Chet Baker…

Stream a good radio station like WBGO.

I would start with a music appreciation class. Learn how to listen to the musicians interacting with each other. Learn how they are listening to each other and then making incredible music with queues to each other. That is what makes jazz and other forms of improvisational music so incredibly, whether rock, bluegrass, jamband or any other. Sometimes I just focus on one instrument then gradually other players seep into my listening space. It’s a wonderful experience, imho 

Any  Steely Dan record

would be a good intro

I found years ago that big band jazz is pretty easy to enjoy & “ understand “ for someone unfamiliar w/ much of jazz as I was. It’s generally more structured w/ less improvisation.

stuartK’s explanation of jazz is excellent & it may sound strange but I really began to appreciate the Grateful Dead after I realized that much of their music follows this jazz format of stating a central theme as a group,  taking turns w/ variations on that theme & then finally returning to that group theme albeit often a bit changed or even expanded. For those who don’t know, Jerry Garcia was a great musician who could play many types of music at a high level.
