Press the tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a small bowl, whisk together the tamari, minced ginger, garlic, and arrowroot powder to create the sauce.
Heat the toasted sesame oil in a large non-stick skillet over medium-high heat.
Add the tofu cubes to the skillet and sear until golden brown on all sides, about 8 to 10 minutes.
Add the broccoli florets and shelled edamame to the pan with a splash of water, covering for 2 minutes to steam-tenderize.
Remove the lid and pour the sauce over the tofu and vegetables, tossing constantly until the glaze thickens and coats everything.
Season with sea salt and black pepper, then garnish with sesame seeds before serving.
