This is what happens when you talk to people on the internet and make a point that needs proving:
Take a couple of nice big bags of dry roasties and a food processor.
Blitz for about 5 minutes, until you have a greasy floury dough texture.
While the processor is running, drizzle in a little oil. The dough with ball up almost immediately into the glorp we all love.
So yeah. It's a thing. And it's intensely savoury!
