Coating the tofu in cornstarch before you cook it gives it a light crust.
Cut tofu into 1/2- to 3/4-inch cubes and pat dry.

Heat 1 tablespoon oil in a wok or large skillet over medium-high heat.
Add the tofu and spread out across the surface of the pan.
Let cook undisturbed for 2 minutes.
Gently turn and stir.
Continue cooking, stirring occasionally, until lightly browned and crispy, 2 to 3 minutes more.
Transfer to a plate.
Reduce heat to medium.
Add the remaining 1 tablespoon oil to the pan.
Add green beans, garlic and ginger; cook, stirring constantly, for 1 minute.
Stir the reserved soy sauce mixture and pour it over the green beans.
Cook, stirring, until thickened, about 1 minute.
Add the tofu and cook, stirring, until heated through, about 1 minute more.
