Press the tofu for 15 minutes to remove excess moisture and cut into 1-inch cubes.
In a small bowl, whisk together the tamari, grated ginger, minced garlic, rice vinegar, and red pepper flakes to create the sauce.
Heat the toasted sesame oil in a large skillet or wok over medium-high heat.
Add the tofu cubes 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, snap peas, and shelled edamame to the skillet.
Stir-fry the vegetables with the tofu for 5-6 minutes until they are tender-crisp.
Pour the prepared sesame-ginger sauce over the mixture and toss well to coat everything evenly.
Cook for an additional 2 minutes until the sauce thickens slightly and the flavors meld.
Garnish with sesame seeds before serving hot.
