Remove tofu from packaging and press between paper towels 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 the sesame oil in a large non-stick skillet or wok over medium-high heat.
Add the tofu to the skillet in a single layer and sear for 3-4 minutes per side until golden brown and crispy.
Add the broccoli florets, sliced red bell pepper, and edamame to the skillet with the tofu.
Stir-fry the vegetables for 5 minutes until they are tender-extending but still vibrant in color.
Stir in the minced garlic and grated fresh ginger, cooking for 1 minute until fragrant.
Pour the tamari over the mixture and toss well to coat everything in the glaze.
Remove from heat and garnish with sesame seeds before serving.
