Remove the tofu from its packaging and press firmly between paper towels for 10 minutes to remove excess moisture.
Cut the pressed tofu into 1-inch cubes and toss them in a bowl with the cornstarch until lightly coated.
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 3-4 minutes per side until they are golden brown and crispy.
Add the broccoli florets, sliced red bell pepper, and edamame to the pan, stir-frying for 5 minutes until the vegetables are tender-crisp.
In a small bowl, whisk together the tamari, rice vinegar, honey, minced garlic, and grated ginger.
Pour the sauce over the tofu and vegetables, tossing constantly for 1-2 minutes until the sauce thickens and coats everything evenly.
Remove from heat, garnish with sesame seeds, and serve warm.
