Combine all ingredients expect the olive oil in the food processor and blend until well mixed. Make sure that the texture is slightly chunky.
Using a 1/3 cup, measure out 5 patties from the black bean mixture.
In a large, nonstick frying pan, heat the olive oil over medium heat.
Place the burgers in the pan and cook about 6-8 minutes on each side, until warmed and the outside is slightly crispy.
Serve with salsa or guacamole, if desired.
