The pairing of tangy herbed goat cheese and grilled zucchini makes for a delicious sandwich filling.
Heat a grill or grill pan over medium-high heat. Combine zucchini, olive oil, salt, and pepper in a small bowl; toss to combine. Grill until lightly browned and tender.
Roll goat cheese in chopped parsley; slice into 8 rounds. Cut rolls in half; spread the bottom halves with olive tapenade, if using. Layer with grilled zucchini, lettuce, and herbed goat cheese; top with other roll half.
