The Onion Volcano

The best part of hibachi when the chef makes a small stack of raw onion rings, puts vegetable oil in it, and lights it on fire whilst it expels steam and flames, like a volcano. (Hence the name).

Them: how was the hibachi dinner last night?
You: it was great, except I missed the onion volcano while I was in the restroom.
Them: aw man, that’s the best part!
