This neat gadget is called an Over-Sink Colander, and it is a handy tool not just for general prep, but for those of us whose kitchens could use an extra bit of "counter" space. Effectively, this gadget makes your sink another counter – and also a place to drain and wash your food.
Rests on the sink with rubber, or on feet. Cutting board can be removed.
This is on sale for an incredible $9.95
