In a large mixing bowl, combine the cubed tofu, diced cucumber, halved cherry tomatoes, diced capsicum, and finely chopped onion.
Add the chopped coriander leaves to the bowl.
In a separate small bowl, mix the plant-based curd, lemon juice, salt, black pepper, and olive oil (if using).
Pour the dressing over the salad mixture and gently toss until everything is well coated.
Serve immediately or refrigerate for 15 minutes to allow the flavours to meld.
