Ok similar thread to Kanda's, but I am in need of help..

DD1 will eat, has no problem with breakfast, no problem with lunch either. Dinnertime is a complete waste of time and energy. She doesn't eat anything I cook for her, even if she has asked for it!
Im so tired, of cooking and handing the dog her dinner, of her not sleeping cause she has an empty tummy. If I ask her to eat something on her plate and she fusses enough she will throw it up immediately after trying it.
Tonight she said the food we cook for her makes her tummy sad. She says that every night. Maybe I am a bad cook, oh I don't know.
I've tried the well then you wait until breakfast thing, and shes fine with it.
Im over trying to make things she will eat, I want to eat so many other things that I love but she wont even contemplate, so I havent bothered cooking them in a long time.
It seems to be a texture thing, a colour thing, a temperature thing, and an overall look thing.... Either way Im stuffed.
So heres the questions,
what are your failsafe meal options to get your kids to eat healthy dinners?
What are your tricks to get them to eat?
What would you do if you were me?
What would you/have you changed to make dinnertime a success?

Im asking you wonderful people for advice, Im at my wits end, in tears every night over this. I hate dinnertime right now and I need to change that.
Please BBers I am in need of some serious help/advice/encouragement....
Please?
