Drain the firm tofu and press it firmly between paper towels to remove excess moisture for a better sear.
Finely dice the red bell pepper into uniform pieces and set aside.
Heat the olive oil in a large non-stick skillet over medium heat until it begins to shimmer.
Add the diced red bell pepper to the skillet and sauté for 3 to 4 minutes until it becomes tender and fragrant.
Crumble the tofu into the skillet using your hands, creating varied textures that resemble scrambled eggs.
Sprinkle the turmeric, nutritional yeast, garlic powder, sea salt, and black pepper evenly over the crumbled tofu.
Add the tablespoon of water to the pan and stir well to help the spices hydrate and coat the tofu in a golden hue.
Cook the mixture for 5 to 6 minutes, stirring occasionally to develop a light crust on the tofu pieces.
Fold in the fresh spinach leaves and toss gently for 1 minute until they are just wilted and bright green.
Transfer the tofu scramble to a bowl and top with the fresh avocado slices before serving immediately.
