Preheat oven to 350 degrees F. Line a baking sheet with a silicone mat or lightly grease. Set aside.
Combine all the ingredients in a food processor. Blend until well mixed and finely chopped.
Spoon mixture into a mixing bowl.
Form mixture into 12 burgers and place on a baking sheet lined with a silicone mat or lightly greased.
Bake burgers for 30-45 minutes until cooked through. The burger will feel firm on the outside and soft in the center.
Remove from heat and let cool for at least 15 minutes on a rack. This is important as it allows the burger to achieve a more consistent burger like texture.
Serve while still warm. Freeze the rest of the burgers or refrigerate and use within two days.
