My son is the same he is really picky with his food, he'll only eat plain pasta, cheese, root vegetables, fruit and sweets of any variety! However at his childminders he eats anything she gives him!
I dread dinner times as its always such a battle, however recently I have started to make it into a game, we all sit together and play who can eat the chicken the fastest, he starts off by saying I don't like it. After he sees his Dad and me playing and laughing he joins in. It took a long time though and a hell of a lot of patience and encouragement. I often do the old reverse psychology "You can't eat all that chicken" that often works!
