Drain the tofu and press between paper towels for at least 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a medium bowl, whisk together the tamari, chili garlic sauce, minced garlic, and grated ginger to create the stir-fry sauce.
Place the tofu cubes in a separate bowl and toss with arrowroot starch, sea salt, and black pepper until evenly coated.
Heat the toasted 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.
Remove the tofu from the pan and set aside; add the broccoli florets, sliced red bell pepper, and edamame to the same pan.
Stir-fry the vegetables for 4-5 minutes until tender-crisp and bright in color.
Return the crispy tofu to the pan and pour the chili-garlic sauce over the mixture.
Toss everything together for 1-2 minutes until the sauce thickens and coats the tofu and vegetables beautifully.
Serve immediately while the tofu is at its peak crispness.
