Press the extra-firm tofu for at least 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 the toasted sesame oil in a large non-stick skillet or wok over medium-high heat.
Add the tofu to the skillet and cook for 8-10 minutes, turning occasionally, until all sides are golden and crispy.
Add the minced garlic, grated ginger, broccoli florets, and sliced red bell pepper to the pan.
Sauté the vegetables for 4-5 minutes until they are tender-crisp and the aromatics are fragrant.
Stir in the shelled edamame, tamari, and chili garlic sauce, tossing everything together for 2 minutes until glazed and hot.
Serve immediately while the tofu is at its maximum crispness.
