Combine chicken and marinade. Mix well and refrigerate at least 24 hours. Drain.
On a hot pan over high heat, grill the chicken for 3-4 minutes each side with the ginger.
Mix in sauce ingrediants and incorporate well. Add cornstarch slurry to thicken as desired. Slightly overthicken as water from the tofu will water it down.
Gently stir in tofu and cover, simmer for 5 minutes.
