Press the extra firm tofu for 15 minutes to remove excess moisture then cut into one-inch cubes.
In a small bowl, whisk together the tamari, rice vinegar, arrowroot powder, and red pepper flakes to create the stir-fry sauce.
Heat the toasted sesame oil in a large skillet or wok over medium-high heat and sear the tofu cubes until golden and crispy on all sides.
Add the broccoli florets, sliced red bell pepper, sugar snap peas, and shelled edamame to the skillet.
Sauté the vegetables with the tofu for five minutes until they are tender-crisp and vibrant.
Stir in the minced fresh ginger and minced garlic, cooking for just one minute until highly aromatic.
Pour the sauce over the tofu and vegetable mixture, tossing constantly for one minute until the sauce thickens and coats all ingredients.
Season with sea salt and black pepper before serving immediately in a bowl.
