Remove the tofu from the package 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, grated ginger, minced garlic, rice vinegar, and red pepper flakes to create the stir-fry sauce.
Heat the toasted sesame oil in a large non-stick skillet or wok over medium-high heat.
Add the tofu cubes to the skillet in a single layer and sear for 3-4 minutes per side until golden brown and crispy.
Add the broccoli florets, sliced red bell pepper, and shelled edamame to the pan with the tofu.
Stir-fry the vegetables for 5 minutes until the broccoli is tender-crisp and vibrant green.
Pour the sauce over the tofu and vegetable mixture, tossing constantly for 1-2 minutes until the sauce thickens and coats everything evenly.
Garnish with sesame seeds and serve immediately while hot.
