Press tofu between paper towels with a heavy object for at least 30 minutes to remove excess water.
Cut the pressed tofu into 1-inch cubes.
In a medium bowl, combine soy sauce, sesame oil, grated ginger, lime juice, salt, and pepper to make the marinade.
Add tofu cubes to the marinade and gently toss to coat. Let marinate for 15-20 minutes, turning occasionally.
While tofu marinates, prepare all vegetables and arrange mixed greens in a large salad bowl.
Heat a non-stick pan over medium heat. Add the marinated tofu cubes, reserving any excess marinade.
Sear tofu for 2-3 minutes on each side until golden brown and slightly crispy on the edges.
Add shredded carrots, sliced cucumber, red bell pepper, and any optional vegetables to the salad bowl with the greens.
Allow the seared tofu to cool slightly for 2-3 minutes, then add to the salad.
Drizzle with any remaining marinade and sprinkle with chopped cilantro and optional toasted sesame seeds.
Gently toss all ingredients together, being careful not to break the tofu cubes.
Serve immediately for the perfect contrast of warm tofu and crisp vegetables, or chill for a refreshing meal.
