Remove the tofu from its packaging and press 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, toasted sesame oil, grated ginger, and minced garlic to create the stir-fry sauce.
Heat the avocado oil in a large non-stick skillet or wok over medium-high heat.
Add the tofu cubes to the pan in a single layer, seasoning with sea salt and black pepper, 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 shelled edamame to the same skillet.
Stir-fry the vegetables for 5 minutes until tender-crisp, adding a splash of water if needed to steam the broccoli.
Return the crispy tofu to the skillet and pour the prepared sauce over the mixture.
Toss everything together for 1-2 minutes until the sauce thickens and coats every ingredient evenly.
Garnish with sesame seeds and serve immediately while hot.
