Press the tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a large 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 over medium-high heat.
Add the tofu to the skillet and sear for 8-10 minutes, turning occasionally until all sides are golden and crispy.
Add the broccoli florets and shelled edamame to the pan, stirring frequently for 4-5 minutes until the broccoli is bright green and tender-crisp.
Stir in the minced garlic and grated ginger, cooking for 1 minute until fragrant.
Pour the tamari over the mixture and toss well for 1-2 minutes to glaze all ingredients.
Remove from heat and garnish with sesame seeds before serving.
