Drain the tofu and wrap it in a clean kitchen towel, placing a heavy pan on top for 15 minutes to press out excess moisture.
Cut the pressed tofu into 1-inch cubes and season with sea salt and black pepper.
In a small bowl, whisk together the tamari, rice vinegar, honey, grated ginger, minced garlic, 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 and sear for 8-10 minutes, turning occasionally until all sides are golden brown and crispy.
Add the broccoli florets, sliced red bell pepper, and shelled edamame to the skillet with the tofu.
Stir-fry the vegetables for 4-5 minutes until they are tender-crisp and bright in color.
Pour the prepared sauce over the tofu and vegetables, tossing constantly for 1-2 minutes until the sauce thickens and coats everything evenly.
Remove from heat and garnish with sesame seeds before serving.
