Press tofu to remove excess moisture and cut into 1-inch cubes.
In a bowl, toss tofu with arrowroot powder, sea salt, and black pepper until evenly coated.
Heat sesame oil in a large non-stick skillet over medium-high heat.
Add tofu to the pan and sear until golden and crisp on all sides, then remove and set aside.
In the same pan, add broccoli, bell pepper, and edamame, sautéing for 4-5 minutes until tender-crisp.
Stir in minced garlic and grated ginger, cooking for 1 minute until fragrant.
Whisk tamari and rice vinegar together, then pour into the pan along with the crispy tofu.
Toss everything together for 1-2 minutes until the sauce thickens and coats the ingredients.
Garnish with sesame seeds before serving.
