Drain and rinse
the chickpeas, then blend them in a blender or
food processor with the remaining ingredients
except the egg and oil.
Turn the mixture into a
bowl and beat in the egg, then cover and chill
in the refrigerator for 30 to 60 minutes, or
longer if more convenient.
Preheat the oven to
180°C/350°F/Gas mark 4.
With wet hands,
shape the mixture into 20 equal-size balls.
Place the falafels on an oiled baking sheet and
flatten them slightly, then brush them with more
oil.
Bake for 20 minutes, turning them over
halfway.
To make the dressing, blend the mint,
garlic and yogurt in the blender or food
processor, turn into a bowl and add salt and
pepper to taste.
To serve, place the falafels
on a serving platter and spoon the dressing over
them. Serve hot.
