Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Press the extra firm tofu for 15 minutes using a tofu press or heavy weights to remove excess moisture, then cut into 1-inch cubes.
In a large mixing bowl, toss the broccoli florets, chopped red bell pepper, and shelled edamame with 0.5 tbsp of olive oil, sea salt, and black pepper.
Spread the vegetable medley in a single layer on the prepared baking sheet and roast for 20 minutes until the vegetables are tender and slightly charred.
While the vegetables roast, whisk together the nutritional yeast and garlic powder in a shallow bowl, then toss the tofu cubes in the mixture until evenly coated.
Heat the remaining 0.5 tbsp of 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, or until each face is golden brown and crispy.
Drizzle the tamari over the tofu in the skillet during the final minute of cooking, tossing quickly to glaze each cube.
Remove the roasted vegetables from the oven and serve them in a bowl topped with the crispy pan-seared tofu.
