In a small bowl start to mix the flax seeds with water. Leave to thicken while preparing the rest.Cook the chickpeas or use precooked ones. Chop onions and garlic. Thaw the peas in cold water. In a high powered mixer or food processor add: Chickpeas, onions, garlic, peas, paprika, lemon, flour, baking powder, parsley – and a generously pinch of salt and pepper. Mix until you have a good well-mixed texture. Afterwards, add the flax seed mix too and carefully mix the ingredients with a spoon. (The mixture will be a little wet and sticky.) Form like round patties with your hands. Heat a pan with 3-4 tablespoons of oil. Fry them shortly until golden on both sides. Flip them halfway through. The result should be crispy, yet soft inside.Serve the patties in burgers or with cold salad and dressing.
