Since villain is so passive, I think you can make a small blocking bet here of around $5 or so and get called by worse without ever getting raised by worse. It's awkward because there's less than a psb behind, but there is value to be had even though some portion of his range just got there. So a smallish b/f looks good. When you shove, you fold alot of worse hands, but of course you're never folding better.
