These Mediterranean stuffed layered loaves are perfect to bring along to a summer picnic - full of mozzarella and tasty, juicy veg, it's a really great change from the usual cheese sandwiches. Not only does it taste delicious, it also looks really impressive too, as you can see all the colours from the different veg and mozzarella in all the layers when you cut through. Make sure you take the time to chill the sandwiches in the fridge for a few hours, as the recipe recommends, because this way the juices from the grilled veg will have time to soak into the bread, not only keeping it extra moist but also adding a really fab flavour to it. This Mediterranean layered sandwich is a great grown-up choice for a picnic, and ideal for sharing with friends! Make the night before so all you need to do is grab them from the fridge before you leave!
