I Have A 12 Year Old Daughter That Is A

I have a 12 year old daughter that is a VERY picky eater and eats very little. The only things I can get her to eat are chicken strips, scrambled eggs, pizza, biscuits and a few other things. Of course she would live off junk if she could but I don't allow that or pop. She eats no fruits or vegetables. I cannot get her to try any new foods. I don't know what to do. Her pediatrician said not to worry about it that she'll eat when she gets hungry, but that doesn't work. She'd rather starve to death before she put a bite of food on her mouth that she didn't want to eat.
