For a vegetarian option, substitute the turkey with grilled halloumi cheese or marinated tofu. Feel free to experiment with other cheeses such as provolone or fontina for the roll-ups. If raspberries are not in season, consider using dried cranberries or chopped strawberries for a similar burst of fruity flavor. The Caprese salad can be made a day ahead to allow the flavors to fully develop. Pack the bento box with a small ice pack to keep the ingredients fresh, especially when packing for lunch at work/school.
