Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Press the tofu between paper towels for 15 minutes to remove moisture, then cut into uniform 1-inch cubes.
Toss the broccoli florets and sliced bell peppers with half the avocado oil, sea salt, and black pepper.
Spread the vegetables in a single layer on the baking sheet and roast for 18 minutes until tender-crisp.
In a shallow bowl, whisk together the nutritional yeast, hemp hearts, and garlic powder.
Heat the remaining avocado oil in a large non-stick skillet over medium-high heat.
Add the tofu cubes and sear for 3-5 minutes per side until each face is golden and crisp.
Drizzle tamari over the tofu in the pan, then immediately toss the cubes in the nutritional yeast mixture.
Serve the crispy coated tofu over the warm roasted vegetables.
