Method:
Put chickpeas, lemon juice, tahini, soy sauce, cumin, coriander, garlic, and 1/4 cup water into a food processor and puree until smooth. Transfer to a bowl, cover, and refrigerate. Before serving, let hummus come to room temperature, then stir in parsley.
Divide hummus between 6 slices of bread and spread out evenly with a knife. Top with remaining slices of bread and press each sandwich down lightly. Using a large cookie cutter (any shape you'd like), cut out the sandwiches and transfer to a platter. Cut the remaining part of each sandwich into geometric
shapes and transfer to the platter, if you like.
Serve immediately, or cover platter with a slightly dampened paper towel and plastic wrap, then refrigerate until ready to serve.
