If the ugly is right, we sometimes use our crazed vegetables as the centerpiece or decoration for a special dinner party.
Takes a bit of extra effort to clean eg a mutant carrot or potato, but the visual effect can be very pleasing.
To us, anyway.
I had a wonderful sack of russet potatoes last year, that were fused in all sorts of ways. We roasted them whole and they made a supremely beautiful dish.
Ugly tomatoes are a bit more tricky, as they often have uneven ripening or just such a scarry surface it's not appealing to eat without resorting to the sauce pot.
