1. In a large saucepan add the oil on a medium heat and fry the onion for 6-8 mins. Add the garlic and cook for a further minute. Tip in the tomatoes and basil and season with salt & pepper. Reduce to simmer for 25 mins.

2. Pre heat the oven to 180 degrees. Pour the beaten egg in a shallow bowl and flour on a separate plate. Lightly dip each side of the courgette slices in the egg followed by the flour. Arrange half the courgette slices on the bottom of a large oven proof dish followed by half of the mozzarella then finally the tomato sauce. Repeat the layers once more, then scatter over the breadcrumbs and pecorino on top!

3. Bake for 30-35 mins until lightly golden.
