"It's a dead ringer for Ahi tuna sashimi. It cuts into glistening slivers that are firm and juicy. And it's got a savory bite."

"But this flesh-like food is not fish. It's made of tomato, and it's what San Francisco chef James Corwell hopes could be one small step toward saving imperiled species of fish, like bluefin tuna."
