Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Press the tofu block between heavy plates and 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 0.5 tbsp of olive oil, sea salt, and black pepper.
Roast the vegetables in the oven for 20 minutes until the edges are tender and slightly charred.
While the vegetables roast, whisk the tamari and garlic powder in a bowl, then toss the tofu cubes in the mixture until coated.
Sprinkle the nutritional yeast over the tofu and toss again until each cube has an even, golden crust.
Heat the remaining 0.5 tbsp of olive oil in a large non-stick skillet over medium-high heat.
Add the tofu to the skillet and sear for 3-4 minutes per side until the exterior is crispy and golden brown.
Divide the roasted vegetables and crispy tofu between plates and serve immediately while hot.
