Press the tofu for 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 brown and crispy on all sides, approximately 8-10 minutes.
Add the broccoli florets, sliced red bell pepper, and snap peas to the skillet, sautéing for 5 minutes until the vegetables are tender-crisp.
Stir in the shelled edamame, minced garlic, and grated fresh ginger, cooking for an additional 2 minutes until aromatic.
In a small bowl, whisk together the tamari and rice vinegar, then pour the mixture over the tofu and vegetables.
Toss everything together for 1-2 minutes until the sauce has thickened slightly and coated all ingredients.
Remove from heat and garnish with sesame seeds and red pepper flakes before serving immediately.
