Sushi, anyone?

Stepping off the subway today, I notice a homeless person's grocery cart parked on the platform. The owner is nowhere to be seen, but the cart bears the trademark anonymous lumps, probably clothes and bedding, hidden inside an assortment of plastic garbage bags. But the thing that really catches my eye is what lies on top: A book of sushi recipes. And so I have to wonder what other necessary implements must also lie within the bags: Sashimi knife, bamboo mat, sake. The question that comes to mind is, if you were a homeless gourmet living sans oven or stove-top, wouldn't sushi be the logical choice? I hear fishing in the East River isn't bad this time of year.
