Water the wooden skewers. Peel garlic and chop finely. Wash oregano, shake dry, chop leaves finely. Wash lemon hot, dab dry and grate peel finely. Squeeze lemon. For the marinade, mix the lemon peel and juice with 2 tbsp. oil, half oregano and half garlic.
Rinse chicken meat cold, dab dry and cut lengthwise into strips about 2 cm wide. Put the strips on the wooden skewers. Turn in the marinade. Cover and leave to marinate in the fridge for approx. 2 hours.
Turn now and then.
For the dip, blend the olives, the rest oregano, garlic and oil with a hand blender. Season to taste with salt and pepper.
Preheat oven (electric cooker: 200 °C/recirculating air: 175 °C/gas: see manufacturer). Let chicken skewers drip off a little. Season with salt and pepper. Place on a baking tray lined with baking paper. Bake in a hot oven for about 20 minutes, turning once.
Serve hot or cold with olive dip.
