Drain and press the tofu for at least one hour. You can wrap the tofu in towels and place a heavy object on top or with a [url:1]tofu press[/url]. While the tofu is pressing, whisk together the miso and water until smooth. Combine with the lemon juice, apple cider vinegar, olive oil, nutritional yeast, dried oregano, garlic powder, salt and pepper. Cut the tofu into small cubes and toss with the marinade. Place in the fridge and marinade for at least 3 hours, preferably longer. Whisk together the dijon mustard, garlic clove and lemon juice until combined. Slowly whisk in the olive oil until combined. Season with salt and pepper. Make the salads! Divide the lettuce, tomatoes, chickpeas, cucumbers and olives among 4 bowls. Top with tofu feta and drizzle on dressing. Serve immediately.
