Put the cooked beans and lentils in a bowl with the lemon juice, spices, coriander/cilantro and black pepper. Mash together.
Add the flaxseed and the spring greens or kale. Mix well.
Divide into six burgers of equal size. I used two spoons to form the shape.
Place the burgers on a baking tray lined with greaseproof paper. Sprinkle half the sesame seeds over them and pat them down.
Bake in an oven at 180 degrees C fan or gas 4 for 10 minutes, then turn over and sprinkle the remaining sesame seeds on the burgers. Again pat the seeds into the burgers. Bake for another 10 minutes on the other side. They are fragile, so turn with care.
Serve with your choice of salad, or fried onions (fried in water), or top with mashed avocado and grated fresh beetroot.
