In a food processor, puree ½ of the beans or mash them, depending on how chunky you'd like your burger to be.
In a medium saute pan over medium heat, add 1-ounce olive oil and all raw vegetables except beans. Saute until translucent. Remove and cool.
Add veggies to the beans and mix thoroughly.
Add all dry ingredients along with the egg.
Thoroughly mix all ingredients and form into 4 patties, cover and refrigerate for 30 minutes, or longer if you have time.
(Refrigerating the mix for a while will help them hold together a little better while cooking)
In saute pan add 1 Tbsp olive oil, and cook patties (~ 2 to 3 minutes per side)
