Heat a non-stick skillet over medium-high heat and add the oil, letting it shimmer and smell slightly nutty.
Add the crumbled tofu directly into the hot skillet, hearing a lively sizzle as it hits the pan. Stir gently, allowing the edges to turn golden and slightly crispy after about 2-3 minutes.
Pour the soy sauce evenly over the tofu, stirring to coat and enhance the savory flavor. Continue cooking for another 1-2 minutes until the tofu absorbs the sauce and develops a richer aroma.
Sprinkle in the nutritional yeast, turmeric, garlic powder, and black salt if using, stirring well to distribute the spices evenly. Cook for 30 seconds until fragrant.
Add the chopped bell peppers to the skillet, stirring to combine. Cook for 2-3 minutes until they soften slightly and brighten in color.
Stir in the chopped spinach and cook for another minute, until wilted and fragrant. The scramble should look vibrant and slightly glossy.
Adjust seasoning to taste, adding more soy sauce or black salt if needed. Remove from heat once everything is heated through and the edges are crispy to your liking.
Serve immediately, garnished with fresh herbs if desired, and enjoy the savory, colorful tofu scramble that’s crispy on the edges and tender inside.
