Press the extra firm tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
Toss the tofu cubes in a bowl with arrowroot powder, sea salt, and black pepper until they are evenly coated.
Heat the toasted sesame oil in a large non-stick skillet over medium-high heat.
Sear the tofu cubes for 8-10 minutes, turning occasionally, until they are golden and crispy on all sides.
Remove the tofu from the skillet and set aside; add the minced garlic, grated ginger, broccoli, and sliced bell pepper to the same pan.
Sauté the vegetables for 5 minutes until tender-crisp, then stir in the shelled edamame.
Whisk the tamari, chili garlic sauce, and rice vinegar in a small bowl to create the stir-fry sauce.
Return the crispy tofu to the pan, pour the sauce over the mixture, and toss for 1-2 minutes until everything is glazed and hot.
