Kai yang (grilled chicken) is a food that is commonly found everywhere in Thailand. The chicken is delicious served with sticky rice or papaya salad (som tum).
There is considerable variety among versions of the dish and associated recipies. Here is one of them, and I might just say this is a very easy recipe and highly satisfying.

Ingredients
2 Chicken Maryland (700g)
1.5 tbsp Oyster sauce
2 tsp Soy sauce
2 tsp sugar
½ tbsp. garlic powder
1 tsp seasoning powder (optional)
Salt
Pepper

Method
Marinate the chicken with all the ingredients and leave in the fridge for at least 3 hr and ideally overnight. There are a few options to cook the chicken. The best and most authentic way is grilling on charcoal. Another option is grilling in the oven. I sonetimes grill in an Air fryer at 180c’ for 15 minutes.
