need veggie burger patty recipe

Please share your fave veggie patty recipe. I had the best veg burger ever this summer made with beans, barley, carrotts and other good stuff. I'd like to find something similar.

 

I use carrots, potatoes, corn and peas, spiced with cumin seeds and ajwain seeds(not sure what that is in english, but you can buy them at your local indian store). I also use some curry masalas at times.
