Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper for easy cleanup.
Wash and dice the zucchini and red bell pepper into small, half-inch pieces to ensure they roast quickly.
Drain the firm tofu and use your hands to crumble it into bite-sized pieces directly onto the prepared baking sheet.
Add the diced vegetables and the rinsed black beans to the sheet pan with the tofu crumbles.
Drizzle the avocado oil over the mixture, then sprinkle evenly with nutritional yeast, turmeric, garlic powder, sea salt, and black pepper.
Toss all ingredients together with a spatula until the tofu and vegetables are well-coated in the spices and oil.
Spread the mixture into a single, even layer and roast for 18-20 minutes, tossing halfway through, until the vegetables are tender.
Remove from the oven, sprinkle with hemp hearts for extra protein, and portion into a glass container for a portable work breakfast.
