I too, am an incredibly fussy eater. I am vegan for a start, and I think I hate more things than I like lol :)
I love anything starchy and plain, this is what I live off: brown rice, bread, rice cakes/corn thins, tomato sauce (ketchup) potatoes, potato chips, fries, corn chips, avocado, bananas, broccoli, oranges, plain pasta, apple puree, anything citrussy - orange juice, orange marmalade. Some of my favourite meals are vegie burgers, pumpkin soup, toast with marmalade, plain rice and vegies...
I am a nightmare to feed as I don't really stretch beyond this. I drive my mother in law crazy.
