Press the extra firm tofu with a heavy object for 10 minutes to remove excess moisture, then cut into small half-inch cubes.
Finely shred the red cabbage and carrots using a mandoline or sharp knife for a consistent crunch.
Slice the cucumber into thin half-moons and the radishes into translucent rounds.
In a small glass jar, combine the extra virgin olive oil, fresh lemon juice, sea salt, and black pepper, then shake vigorously until emulsified.
Place the cubed tofu, shredded cabbage, carrots, cucumber, and radishes in a large mixing bowl.
Drizzle the lemon-herb dressing over the vegetables and toss thoroughly to ensure every ingredient is evenly coated.
Gently fold in the hemp hearts, pumpkin seeds, chopped parsley, and chopped basil just before serving to maintain their texture.
