I've done a bit of experimentation with veggie burgers, and have found some really great recipes, including this wonderful Garbanzo Bean Burger from my favorite cookbook, Super Natural Cooking by Heidi Swanson.
The following burger uses similar elements as Heidi's, but the differences between the two are quite significant (I opt to use a bun, for one), and I really like the spinach-feta addition. Please enjoy!
