Press the extra firm tofu for at least 15 minutes to remove excess moisture, then cut into 1-inch cubes.
Season the tofu cubes evenly with sea salt and black pepper.
Heat the toasted sesame oil in a large non-stick skillet or wok over medium-high heat.
Add the tofu to the pan and sear until golden and crispy on all sides, which should take about 8-10 minutes.
Add the broccoli florets and shelled edamame to the skillet along with a small splash of water; cover with a lid to steam for 3 minutes.
In a small mixing bowl, whisk together the tamari, rice vinegar, grated fresh ginger, minced garlic, and sriracha.
Remove the lid from the skillet, pour the sauce over the tofu and vegetables, and toss for 1-2 minutes until the sauce has thickened and coated everything.
Garnish with sesame seeds and serve immediately while hot and crispy.
