Mix the ¼ cornstarch, garlic powder, and black pepper in a large bowl until combined. Once combined, add the tofu cubes and toss until they are evenly coated on all sides.
350 g extra-firm tofu, ¼ cup cornstarch, ½ tsp garlic powder, ¼ tsp black pepper
In a large pan, warm the sesame oil over medium-high heat. Once hot, add the coated tofu cubes and cook, turning occasionally, until they are golden and crispy on both sides. This will take about 4 to 5 minutes per side, 10 minutes total. Once done, remove cooked tofu from pan and place in a large bowl.
1 tbsp sesame oil
Remove the pan from the heat and add 1 cup water and 1 tbsp tamari. Return the pan to the heat and cover with the lid.
1 cup water, 1 tbsp tamari
Once the water is bubbling and you see steam, reduce the heat to medium and add the broccoli. Cover with the lid once more to steam the broccoli, which should take about 5 minutes. You'll know the broccoli is done when it has brightened in color.
5 cups broccoli florets
Once broccoli is steamed, drain and set aside.
