What Are You, Mystery Stir-Fry Veggie?

Listening to Beastie Boys just minding my own I ordered up some stir-fry speed-dial on my phone.
It got here pretty fast they’re just up the block and I tip pretty well it’s known at Happy Wok.
So I’m chomping on my eats thinking stir-fry’s the shiz when I come upon a veggie with no clue what it is.
It looks kinda like a potato but ain’t no stir-fry spuds Maybe a hunk of onion or garlic dare I test my taste buds?
Carrots, green beans and peppers I think we’d be agreeing are quite easy to discern just by looking and seeing.
Those are off of the table but then what could be left: If this is baby corn I’d be concerned for the chef.
A rare colorless mushroom? The stem of a broccoli? Some unchopped ginger? What the hell could this be?
Come on now, mystery veggie? What are you, what? Oh, hold the phone, yo it’s a water chestnut.
