Press the tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a medium bowl, toss the tofu cubes with arrowroot powder, sea salt, and black pepper until evenly coated.
Heat a large non-stick skillet over medium-high heat and add the toasted sesame oil.
Sear the tofu for 8-10 minutes, turning occasionally, until all sides are golden brown and crispy.
Add the broccoli florets, sliced bell pepper, and edamame to the skillet, sautéing for 5 minutes until the vegetables are tender-crisp.
In a small jar, whisk together the tamari, rice vinegar, grated ginger, and minced garlic.
Pour the sauce over the tofu and vegetables, tossing for 2 minutes until the glaze thickens and coats everything evenly.
Remove from heat and garnish with sesame seeds before serving hot.
