Press the tofu between paper towels for 10 minutes to remove excess moisture, then cut into 1-inch cubes.
In a small bowl, whisk together the tamari, rice vinegar, grated ginger, and minced garlic 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 5-7 minutes, turning occasionally until the edges are golden brown and crisp.
Add the broccoli florets, sliced red bell pepper, and edamame to the skillet with the tofu.
Sauté the vegetables for 4-5 minutes until they are tender-bright but still have a slight bite.
Pour the prepared sauce over the tofu and vegetables, tossing quickly to coat everything evenly.
Season with sea salt and black pepper, then cook for an additional minute until the sauce thickens slightly.
Remove from heat and garnish with hemp hearts and sesame seeds before serving.
