What kind of vegetables? Raw or cooked? The veggies might be killing them. You might try looking for one with blades instead of wires, but even they say only use them on eggs and soft fruit.

I have an Ikea Mulig rack. Holds a lot of clothes. I also have one of those collapsible wooden ones, like this. A little wobbly but it doesn't fall over.

It reminded me of the gas pipeline cut in Princeton.
