You probably know these kind of gadgets that help you cut vegetables quickly:
I've had a couple of them over the years so I could make simple salads quickly, but I always ended up throwing them away after a few uses, for a simple reason: They're difficult to clean. You may be saving 3 minutes by using a fancy chopper rather than a knife and a cutting board, but then you're losing these 3 minutes right back because you can't put the chopper in the dishwasher, so you have to carefully clean all of its twists and turns. Some of them have parts that you can put in the dishwasher, but so far I haven't seen one where the main part, the one that has the fancy mechanism, can be put in the dishwasher.
Do you happen to know a salad chopper that could be put in the dishwasher entirely for easy cleaning?
