This vegetarian twist on the classic French sandwich features grilled zucchini slices instead of ham. The zucchini is marinated in a flavorful mixture of olive oil, garlic, and herbs, then grilled until tender and slightly charred. The grilled zucchini is layered with melted cheese and sandwiched between slices of crusty bread. The sandwich is then grilled until the cheese is melted and the bread is crispy. It's a delicious and satisfying vegetarian option that is perfect for lunch or a light dinner.
