Preheat oven to 400 degrees F. In a bowl, whisk together chicken stock, brown sugar, 1 tablespoon sesame oil, garlic cloves, soy sauce and vinegar. Set aside.

Heat a large oven-proof skillet over medium-high heat. Toss chicken with salt, pepper and flour. Add olive oil and 1 tablespoon sesame oil to skillet, and once hot, add chicken in a single layer. Cook until seared and golden on one side, then flip and cook until golden again, about 2-3 minutes. Pour chicken stock mixture over top and toss to coat, then turn off heat. Place skillet in oven and bake for 20 minutes. Remove and cover with sesame seeds. Serve with veggie of your choice and brown rice.
