Preheat your broiler and line a baking sheet with parchment paper.
Press the extra firm tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a small bowl, whisk together the tamari, toasted sesame oil, rice vinegar, grated ginger, and minced garlic.
Toss the tofu cubes with half of the prepared sauce, sea salt, and black pepper, then spread them in a single layer on the baking sheet.
Broil the tofu for 8 to 10 minutes, flipping halfway through, until the edges are golden and crispy.
While the tofu broils, heat a large non-stick skillet over medium-high heat and add the chopped bok choy, sliced mushrooms, carrot matchsticks, and edamame.
Pour the remaining sauce over the vegetables and sauté for 5 minutes until they are tender-crisp.
Plate the vegetable medley and top with the broiled tofu, finishing with a sprinkle of sesame seeds.
