Mix all the ingredients (chicken keema, beaten egg yolks, chopped onion, chopped ginger, chopped garlic, red chilli powder, chopped green chillies, chopped fresh coriander leaves, salt and fresh black pepper crushed) together very well in a bowl.
Transfer it in an airtight container and rest it for 2 hrs in a refrigerator. After that, take it out and make equal sized kebabs using your hands.
Griddle them two or three at a time on a hot Tawa with 1 tbsp oil. Cook until they look golden from the underside. Keep the flame on medium heat. Flip them and cook the other side. Repeat the same process for cooking all the prepared kebabs. Serve hot with seasoned curd or green chutney along with sliced onions.
