My guy's ex-wife was the same way. His kid (5 at the time) moved in and was insistent that he didn't like vegetables because they were gross. I cooked him all the foods he said he didn't like like asparagus, which is now his favorite vegetable. Turns out his mom always told him he wouldn't like them. It's easy to see how she blew up herself and her daughters after the divorce. Hell, when his step-daughters visit, they eat the veggie they think they don't like and enjoy them.
