Press the tofu for 20 minutes to remove excess moisture, then cut into 1-inch cubes.
Season the tofu cubes evenly with sea salt and black pepper.
Heat a large non-stick skillet over medium-high heat and add half of the toasted sesame oil.
Sear the tofu cubes until golden brown and crispy on all sides, approximately 8-10 minutes, then remove from the pan and set aside.
In the same pan, add the remaining sesame oil along with the broccoli florets and sliced red bell pepper, sautéing until tender-crisp.
Stir in the shelled edamame, grated ginger, and minced garlic, cooking for 1-2 minutes until highly fragrant.
Return the crispy tofu to the pan and pour in the tamari and rice vinegar, tossing gently to coat all ingredients.
Garnish the stir-fry with sesame seeds and serve immediately while hot.
