The tomato was considered dangerous to eat in Europe because of its relationship to the Nightshade family, so no one ate it. One day, some Italian <unpublishable> <unpublishable> decided to cook it into a sauce and give it to a woman, so she would get drugged and he could take advantage of her.
She didn't get poisoned, and he invented what we currently know as Italian cuisine.
So, my guess is going to be "by less than ethical ways".
