This is NOT especially a substitute hamburger, more like a potato patty with a middle eastern flair. But it is filling and works well in pita with tahini, tomatoes, lettuce, etc (or dh likes his with ketchup...oh well). If you want a richer flavor, you could add an egg and some zippy spices; we use this for fasting days when we are looking for low key vegan foods so it is deliberately pretty mild. (The kids also prefer it this way anyway...and eat theirs with ketchup as well - it's dh's fault!) I do sometimes add rosemary, basil, a splash of olive oil, etc...this is more of a 'base' recipe to which you can add on. Also good with sauteed mushrooms and onions, baked potato-type toppings, or spaghetti sauce on it...be creative! :o) I leave out the powdered milk when we want to go fully vegan and truthfully have never noticed a difference one way or the other so don't worry if you don't include it. You can also shaped them into balls instead of patties and serve with tahini sauce (sesame seed dressing) for appetizers.
