How to Make It
In a large skillet, heat the olive oil until shimmering. Add the onion and cook over high heat, stirring, until softened and lightly browned, about 5 minutes. Add the tomatoes, cinnamon sticks, star anise and ginger and season with salt and pepper. Add the chicken breasts and season with salt and pepper. Cover and cook over moderate heat, turning the chicken once, until cooked through, about 15 minutes.
Transfer the chicken to plates. Stir the basil into the sauce. Spoon the sauce over the chicken and serve with couscous.
