Press the extra firm tofu for at least 20 minutes to remove excess moisture, then cut into 1-inch cubes and season with sea salt and black pepper.
In a small glass bowl, whisk together the tamari, rice vinegar, sriracha, and toasted sesame oil to create the stir-fry glaze.
Heat the avocado oil in a large non-stick skillet or wok over medium-high heat until shimmering.
Add the tofu cubes to the skillet in a single layer and sear for 8-10 minutes, turning occasionally until all sides are golden brown and crispy.
Toss in the broccoli florets along with a tablespoon of water; cover the pan for 2 minutes to lightly steam the broccoli until it is bright green.
Remove the lid and add the minced garlic, grated fresh ginger, and shelled edamame, sautéing for 2 minutes until the aromatics are fragrant.
Pour the prepared sauce over the tofu and vegetables, tossing constantly for 1 minute until the glaze thickens and coats every piece evenly.
