Finely chop parsley in food processor. Transfer to another bowl and set aside.
Cut carrot into large pieces, place in food processor, and pulse until finely chopped.
Add beans, seasonings, oil, lemon juice, and starch and pulse just until mixed but still slightly chunky.
Add finely diced onion, parsley, and quinoa and process just until mixed. Do not over-process; you want the mixture thoroughly combined but not mushy.
Using approximately 2 tablespoons of mixture at a time, form into patties. (I use a cookie scoop to form the mixture into quick, nice, neat balls and then I gently pat them flat to form quick, nice, neat patties.)
Heat small amount of oil in a non-stick skillet. Cook patties until browned on bottom. Turn over and cook until the other side is browned.Serve hot.
Notes
If beans are well drained and quinoa is cooked correctly, the patties should hold together firmly. However, if you find that the patties fall apart when cooking them, simply stir one tablespoon flax meal into mixture OR place mixture into refrigerator to chill before shaping into patties.
