Bring 2 cups (480ml) of water to a boil. Rehydrate the soy chunks. Add into a medium-sized bowl. Cover them with boiling water, enough to cover and submerge them completely. Let them sit for 10 minutes. Mix around with a spoon to get them evenly distributed in the water. *you may need more than 2 cups of water depending on your bowl size.
After 10 minutes they will increase in size. Strain the water. Then, use a paper towel to squeeze the excess water from the soy chunks. Place them back in a bowl.
Coat in 2 teaspoons (10g) of cornstarch, salt, and black pepper.
I like to lightly spray a large non-stick pan with spray oil but you can skip that if you prefer. Add the soy chunks. Cook for 5 to 7 minutes until golden brown on each side over medium heat. Shake and toss the pan around to cook the sides evenly.
Meanwhile, prepare the sauce. Mix the remaining cornstarch with 3 tablespoons (45ml) of water to make a slurry.
In a jar combine the soy sauce, maple syrup, cornstarch slurry, seasonings, sesame seeds, and ½ cup (120ml) of water to make the sauce. Shake together. You can also do this in a bowl, I just find it easier to shake everything up.
Then, pour half of the over the soy chunks. Cook for a few minutes for the cornstarch to thicken, mixing constantly. If the sauce looks too thick you can always add in more water.
Remove from the heat and add the sesame oil. Toss to coat.
Garnish with more sesame seeds, red pepper flakes, and green onions. Enjoy.
