If using corn flakes, process to a fine crumb. Stir in the cheese, onion, garlic powder, seasoned salt, oregano, thyme and pepper.
Rinse the chicken and pat dry. Coat with the yogurt and roll in the crumb mixture.
Place meaty side up on a lightly greased 15x10x1 inch pan. Drizzle with the butter and sprinkle with the sesame seeds.
Bake uncovered in your preheated oven for 45-55 Minutes. It only took mine 37 minutes to cook this as I have a very hot oven. Check the chicken at the 35 minute mark to see if it's done. You don't want to dry it out.
You can also put the crumb mixture into a large zip lock bag and drop one piece at a time of the yogurt covered chicken. Place of the baking pan and drizzle with the butter and sesame seeds.
Either way you do this it's quite messy, but is worth the effort. Enjoy!
