Press and Drain Tofu: Wrap the tofu in a clean kitchen towel and set a heavy object on top for about 15-20 minutes to press and drain. You can also use a tofu press.
Blend Tofu and Initial Olives: Blend the tofu until smooth in a food processor. Add 1 cup of the green olives with pimento (and walnuts if using) and blend until the mixture is well combined but retains some texture.
Incorporate Flavorings: Add the garlic powder, capers, parsley, lemon juice, lemon zest, and coconut aminos. Pulse the food processor a few times to mix everything evenly.
Season: Taste the mixture and add black pepper as needed. Adjust the seasoning to your preference.
Add Remaining Olives: Chop the remaining 1/4 cup of olives and stir them into the mixture by hand or pulse briefly in the food processor to maintain chunky pieces.
Refrigerate (Optional but Recommended): Refrigerate the dip for about 30 minutes to 1 hour for enhanced flavor and texture.
Serve and Enjoy: Transfer the dip to a serving bowl, garnishing if desired. Enjoy with whole grain crackers, vegetable sticks, or as a spread.
