How can I get my kid to love (or just like) healthy foods?

It's been a constant struggle for me with my 7 year old. She is such a picky eater, and has the worst eating habits and it drives me crazy each time. But now that her brother has started on solids, I would constantly tell her that her brother would be looking at her a lot so she has to send a good example. It makes it a little easier, because she knows what's good for her (she just hates the taste). Otherwise, I would occasionally ask her what does she want to be when she grow up (it varies every week) and I would say so you have to grow up and strong right! Hahah
