I haven't made banana peels specifically, but I have made this for some vegan guests before (as part of a larger dish) and while I wouldn't say it's bacon, it hits all the same notes: https://www.seriouseats.com/crispy-smoked-mushroom-bacon-bit...

Now I have to try it. Thanks for both links!

Maybe it's like bacon in the same way that spaghetti squash is like spaghetti? (Shape only)
