Press the tofu for at least 20 minutes to remove excess moisture, then cut into 1-inch cubes.
In a medium 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 with a tablespoon of water, covering for 2 minutes to lightly steam.
In a small jar, whisk together the tamari, chili garlic sauce, minced ginger, and minced garlic.
Pour the sauce over the tofu and vegetables, tossing constantly for 1-2 minutes until the glaze thickens and coats everything.
Remove from heat and garnish with sliced green onions before serving.
