In a large mixing bowl, combine the tomatoes, cucumber, olives, lettuce, onion, chickpeas, and vinaigrette. Remove the tofu feta from its marinade and add it to the bowl. Toss everything well.
Taste and add either more of the vinaigrette or more of the tofu feta marinade, as you like. Fold in some cashew parmesan, if desired. Serve with pita wedges.
