That is good for chopping tomatoes and onions? I am sick of oniony hands and tomatoes irritate my skin. I have one of those pushy down cutter things but it doesn't do the job. I don't want to get out my massively heavy food processor, I still have the tiny one from when dc were babies but I have to cut the food up to get it in there which defeats the object.
I just saw this advertised which looked like it might do the job here but reviews on amazon specifically mention it being no good for tomatoes and onions!
