Now peel the onion and garlic and chop them roughly. Finely chop the coriander leaves and add them together with the garlic and onion to the bowl.
Break the egg and lightly beat the egg white and yolk. Switch on the food processor to medium speed and blend in the beaten egg and breadcrumbs. Season with black pepper and salt.
Once the mixture has a good substance, stop the food processor and shape the mixture into four equal-sized patties/burgers of 2-3cm thick. Heat the oil in a grill pan and grill the burgers on a medium heat for approx. 4-5 minutes on each side (medium rare).
Now place the burgers and sliced red onion in a pita bread or between thick slices of bread and top them with the sauce. Finish with your favourite topping (avocado, tomato, rocket salad …)
