Press the tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a bowl, toss tofu cubes with arrowroot powder, sea salt, and black pepper until evenly coated.
Heat toasted sesame oil in a large non-stick skillet over medium-high heat.
Add tofu to the skillet and sear until golden brown and crispy on all sides, about 8-10 minutes.
Remove tofu from the pan and set aside; add broccoli, bell pepper, and edamame to the same pan with a splash of water to steam-sauté until tender-crisp.
Whisk together coconut aminos, rice vinegar, minced ginger, and minced garlic in a small bowl.
Return tofu to the pan, pour the sauce over the vegetables, and toss for 2 minutes until the glaze thickens and coats everything.
Garnish with sesame seeds and serve immediately.
