Press the firm tofu between paper towels for 5 minutes to remove excess moisture, then crumble it into small pieces using your hands or a fork.
Heat the avocado oil in a large non-stick skillet over medium heat, then add the diced red onion and red bell pepper.
Sauté the vegetables for 4-5 minutes until the peppers are tender and the onions are translucent.
Add the crumbled tofu to the skillet along with the turmeric, cumin, garlic powder, sea salt, and black pepper, stirring well to coat the tofu in the golden spices.
Stir in the black beans and fresh spinach, cooking for another 2-3 minutes until the spinach is wilted and the beans are heated through.
Sprinkle the nutritional yeast over the mixture and stir to combine, creating a savory, cheesy flavor profile.
Warm the whole wheat tortilla in a separate dry pan or microwave for 15 seconds until pliable.
Place the tofu scramble in the center of the tortilla, fold in the sides, and roll tightly into a burrito.
