In a bowl, combine all the ingredients. Set aside.

In a large bowl, dredge the tofu in the cornstarch. Shake to remove any excess and set aside on a plate.

In a wok over high heat, heat oil. Fry half of the tofu at a time until lightly browned. Season with salt and pepper. Remove the tofu from the wok and drain on paper towels.

In the same wok, fry the onions, ginger and garlic for 1 to 2 minutes. Add oil, if needed. Add the sauce and bring to a boil. Add the tofu and cook, stirring to warm through, and coat thoroughly with the sauce.

Serve with rice and broccoli.
