Potato and onion are natural choices. I think you could add just about any root, tuber or bulb crop. So, beets, parsnip, carrot and you name it are all fair game.
I've had failures with sawdust and sand. I've had failures with stuff just left in bags. I expect some loss.
What really gets me thinking is about other stuff like cucumbers, tomato, corn and lettuce. Hell. I'll try anything just to find out. Fresh water seems to be an essential. But, apples off gas. What happens if you put lettuce in a Tupperware box with peat and water for a year? Covered. Buried. I wonder.
