Ever try washing it a bunch of times with some fabric softener? I did that with a super stiff denim and it helped a little. You could also try beating it up on purpose, like dragging it behind a car on a dirt road or something crazy. That canvas is meant to lay flat, so it's gonna fight you. Maybe try sanding the high-wear spots like the elbows and collar to force some breakdown.

But does the food still taste good without all that oil?
