Press the extra firm tofu for 15 minutes using a tofu press or heavy skillet to remove excess moisture, then cut into 1-inch cubes.
In a small glass bowl, whisk together the tamari, rice vinegar, grated fresh 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 until shimmering.
Add the tofu cubes to the skillet in a single layer and sear for 3-4 minutes per side until each face is golden brown and crispy.
Incorporate the broccoli florets, sliced red bell pepper, and edamame into the skillet, sautéing for 5 minutes until the vegetables are tender-crisp.
Season the mixture with sea salt and black pepper, then pour the prepared sauce over the tofu and vegetables.
Toss everything continuously for 1-2 minutes until the sauce has thickened and evenly coated all ingredients.
Remove from the heat and finish the dish with a drizzle of toasted sesame oil and a garnish of sesame seeds before serving.
