Let the grated cucumber stand for 10 minutes.
In a blender, mix the tofu, lemon juice, garlic, salt, coriander, cumin, and cayenne pepper until completely smooth.
Squeeze the cucumbers to remove excess moisture and combine with the red onion. Stir in the tofu mixture.
Chill 2 to 3 hours before serving. Serve with crispy pita chips.
