Method

step 1

To make the pastry, whizz the flour and butter in a food processor until it resembles breadcrumbs. Stir in the Grana Padano, then the egg, and bring together to make a dough. Wrap in clingfilm and chill for 20 minutes.
step 2

To make the filling, cook the peppers and onion in 1 tbsp olive oil until very soft, about 15 minutes, then season.
step 3

Heat the oven to 190C/fan 170C/gas 5. Roll out the pastry to 20p thickness. Line a shallow tart tin (about 23cm) with the pastry, fill with baking parchment and beans, and blind bake for 10 minutes. Take out the paper and beans and bake for another 5 minutes.
step 4

Allow to cool a little, then spread base with the Dijon and sprinkle over the gruyère. Top with the pepper/onion mix, then a layer of tomato slices and the olives. Season really well and put back in the oven for another 15-20 minutes until the tomatoes are tender and pastry is cooked through and crisp. Scatter over basil before serving.
