Split Pea Soup. Still can't even look at that stuff! When I was young, probably about 4, my mother made that crap for dinner on Halloween night. Told me that I couldn't go trick or treating til I cleaned my bowl. (and, as an added threat, we would get our "leftover" food cold in the morning for breakfast if we didn't clean our plates) ..... I cried and cried and she would not give in. Finally she left the room and my teenaged brother took pity on me and ate it all.....
I swore I would never do that to my children.... and I never have!!!
