Drain the extra firm tofu and press it between paper towels for 10 minutes to remove excess moisture, then cut into 1/2-inch cubes.
In a small bowl, whisk together the lemon juice, olive oil, dried oregano, garlic powder, sea salt, and black pepper to create the dressing.
Heat a non-stick skillet over medium-high heat and add the tofu cubes, searing for 3-4 minutes per side until golden brown and crispy.
While the tofu cooks, place the chopped kale in a large mixing bowl and massage it with a tiny splash of lemon juice for 1 minute until softened.
Add the cooked quinoa, shelled edamame, diced cucumber, and nutritional yeast to the bowl with the kale.
Transfer the warm, crispy tofu to the bowl and drizzle the lemon-herb dressing over all the ingredients.
Toss everything thoroughly to ensure the quinoa and tofu are evenly coated in the dressing before serving.
