Here is what looks like a good alternative to the hamburger. This is strictly vegetarian, but it has everything in it that I like. I would use the Garbanzo beans instead of the Fava beans. Give it a try. See what you think. Cheers!

Felcitously & shifa = بالهنا والشفاء = Enjoy your meal = Bon appétit

That really looks easy to do and it looks like you can add whatever herbs you want. Have fun with this one.
