Press the tofu between paper towels for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a small bowl, whisk together the tamari, rice vinegar, grated ginger, and arrowroot powder to create the glaze.
Heat the toasted sesame oil in a large skillet or wok over medium-high heat.
Add the tofu cubes to the skillet, seasoning with sea salt and black pepper, and sear until golden brown on all sides.
Toss in the broccoli florets and shelled edamame, adding a tablespoon of water to help steam the vegetables for 3 to 4 minutes.
Add the minced garlic and cook for 30 seconds until fragrant.
Pour the prepared glaze over the tofu and vegetables, stirring constantly for 1 minute until the sauce thickens and coats the ingredients.
Garnish with sesame seeds and serve warm.
