An option for those chicken pieces would be using two, parallel, bamboo skewers. Just burn or trim excess length for your cooking vessel. A single skewer allows for a single piece of whatever the item is to be difficult and spin back to the cooked side... This happens a lot with mushrooms...
At a penny a skewer, it is worth the additional cost to me for speed and convenience.
Don't forget to give them a twist, to free the food, for easier skewer removal.
If nothing else use the oven or an air fryer, I guess...
Good luck!
