Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Drain the tofu and press it between heavy plates and paper towels for at least 10 minutes to remove excess water, then cut into 1-inch cubes.
Place the broccoli florets and sliced bell peppers on the baking sheet, toss with half of the olive oil, sea salt, and black pepper.
Roast the vegetables in the oven for 15 to 20 minutes until they are tender and show slight charred edges.
While vegetables roast, heat the remaining olive oil in a large non-stick skillet over medium-high heat.
Add the tofu cubes to the skillet in a single layer and sear for 3 to 4 minutes per side until each face is golden brown and crispy.
In a small bowl, whisk together the tamari, garlic powder, and ground ginger.
Reduce the skillet heat to low, pour the tamari mixture over the tofu, and toss for 1 minute until the glaze is thick and sticky.
Divide the roasted vegetables and seared tofu onto plates and serve immediately.
