Finely chop the olives and mix in a bowl with the ground chicken, salt and pepper.
Heat some oil in a pan and after shaping 2 chicken patties using either your hands or a burger mold place them in the hot oil. A handy tip is to wet your hands or the mold to prevent sticking. Ground chicken is generally a lot stickier than beef or pork.
Fry the patty for 3-4 min of each side on a medium heat till cooked through. Then place the patty between two lettuce leaves and enjoy!
