Use your hands to tear the tofu into bite-sized chunks.

Heat the oil in a large pan or wok over medium-high heat. Add the tofu and fry on the first side until golden brown. Stir and toss to fry on the other side.

Meanwhile, combine all the ingredients for the stir fry sauce and stir well to dissolve the cornstarch.

Push the tofu to one side of the pan, lower the heat to medium, and add the ginger and garlic into the empty space. If needed, add another drizzle of oil on top to get it started frying. Fry until soft and fragrant - 30 seconds to a minute.

Add the spinach and stir fry until wilted. Allow any excess water in the bottom of the pan to evaporate.

Pour the stir fry sauce on top and simmer, while stirring, until it’s thickened and coats the tofu.
