Cut an onion in half and slice it lengthwise. Chop the garlic into medium-sized pieces and put both ingredients into a bowl.
Prepare the chicken by cutting it into 3-4 cm size pieces and placing it in the bowl with garlic and onions. Add spices and mayonnaise, mix well, and leave in the fridge for several hours or overnight for best results.
Soak bamboo roasting sticks in cold water for at least 30 minutes to prevent them from burning quickly in the oven.
Preheat the oven to 200°C.
Thread 3-4 pieces of chicken onto a bamboo stick. One portion consists of 3 sticks, but if you're extra hungry, you can use 4 sticks.
Place the chicken skewers on a baking sheet and make sure they do not touch the bottom of the sheet. You can use one bamboo stick to thread through 3-4 chicken sticks to make flipping them over easier.
Cook for 9 minutes, then flip the chicken skewers and cook for another 9 minutes.
Serve with rice, fresh salad, mushroom sauce, or Greek yogurt sauce.
