Press the tofu for 15 minutes to remove excess moisture, then cut it into 1-inch uniform cubes.
In a medium bowl, toss the tofu cubes with arrowroot starch, sea salt, and black pepper until evenly coated.
Heat the avocado oil in a large non-stick skillet over medium-high heat and sear the tofu until golden and crispy on all sides.
Add the broccoli florets and shelled edamame to the skillet, sautéing for 3 to 4 minutes until the vegetables are tender-crisp.
In a small jar, whisk together the tamari, toasted sesame oil, minced garlic, and grated fresh ginger.
Pour the sauce over the tofu and vegetables, tossing quickly to coat until the glaze thickens and becomes glossy.
Remove from the heat and garnish with sesame seeds before serving immediately.
