Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Press the tofu between layers of paper towels for 10 minutes to remove excess moisture, then cut into 1-inch cubes.
Place the broccoli florets and sliced red bell peppers on the baking sheet, tossing them with half of the olive oil, sea salt, and black pepper.
Roast the vegetables for 15-20 minutes until they are tender and show slight charred edges.
While the vegetables roast, whisk together the tamari, garlic powder, and nutritional yeast in a small bowl to create a savory seasoning blend.
Heat the remaining olive oil in a large non-stick skillet over medium-high heat.
Add the tofu cubes to the skillet and sear for 3-4 minutes per side until each face is golden brown and crispy.
Sprinkle the nutritional yeast blend over the tofu in the pan, tossing quickly for 30 seconds to coat every piece.
Divide the roasted vegetables onto plates and top with the crispy seasoned tofu cubes.
