Mine never did that. So I'm just going to talk out of my ass here for a minute...

I think if I were in your shoes, I would only give her half of what you would normally give her. That way you've taken away her opportunity to throw the remaining food, since she'll finish the small amount and probably still be hungry. Then she'll have to ask for more. When you give her more, give her one bite at a time so she continually asks for it (and learns to verbalize her wants and needs rather than act out).
