The next time and effort saving item is my vegetable chopping board. It is another of the things I take around with me as it is so useful.
The downward curved lip fits over the edge of the worktop and the little feet hold it in place. It is a good size and cleans easily. Moveover it is simple to slide whatever I've chopped (or the peelings) off and into the appropriate container.
Teamed with a good knife, it is invaluable!
