Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
Dice the zucchini, red bell pepper, and red onion into bite-sized pieces and spread them evenly across the prepared baking sheet.
Drizzle the vegetables with avocado oil and sprinkle with a pinch of sea salt and black pepper, tossing to coat thoroughly.
Roast the vegetables in the oven for 15 to 20 minutes, or until they are tender and show slight golden-brown edges.
While the vegetables roast, drain the firm tofu and pat it dry with a clean kitchen towel to remove excess moisture.
Crumble the tofu into a large non-stick skillet over medium heat using your hands or a spatula to create egg-like curds.
Stir in the nutritional yeast, ground turmeric, garlic powder, sea salt, and black pepper until the tofu is evenly coated and yellow.
Rinse and drain the black beans, then add them to the skillet with the tofu, cooking for 5 to 7 minutes until heated through.
Remove the roasted vegetables from the oven and gently fold them into the tofu mixture before serving warm.
