I marinated the tofu in the seasoned yogurt overnight but if you're doing it same day make sure you give it minimum 1 hour to develop some flavors. If you're skipping the marinade, coat the tofu in cornstarch and seasonings and crisp it up in the pan and add to the sauce after you've simmered it for the total time. So basically, do whatever you want to your protein and just make the sauce cause that's the real magic here.
