Press the extra firm tofu for 15 minutes to remove excess water, then cut into 1-inch cubes.
In a small bowl, toss the tofu cubes with nutritional yeast, sea salt, and black pepper until evenly coated.
Heat avocado oil in a large non-stick skillet over medium-high heat and sear the tofu until golden brown on all sides.
In a separate jar, whisk together the white miso paste, rice vinegar, toasted sesame oil, grated ginger, and water until smooth.
In a large serving bowl, combine the mixed baby greens, sliced cucumber, shredded carrots, and shelled edamame.
Top the salad with the warm pan-seared tofu, drizzle with the miso dressing, and sprinkle with hemp seeds before serving.
