Veggie burger

Hi all, first time posting anything here so please be nice. I am after a really nice veggie burger recipe. I have a lush chickpea burger so not after that kind of thing and not after a beanburger style one either (sorry if I am being picky) , I want a good old burger jam packed with vegetables! I have tried to make one before but it was too wet and didn't hold together and only tasted ok. Please help!
