Step 1

Grease a 27.5 x 17.5cm tin with a little olive oil.Place the olives and parsley into a food processor and blitz until roughly chopped but not smooth. Spoon into a bowl, mix in the Parmesan and set aside.

Step 2

In a large saucepan, bring the stock to the boil, whisk in the polenta and reduce the heat to low. Simmer, stirring, for 5 minutes until thick and less grainy. Remove from the heat, stir in the olive mixture and tip into the prepared tin. Set aside for 20 minutes to cool and set.

Step 3

Turn the polenta slab out onto a board. Cut into 20 equal-sized pieces. Put the sesame seeds into a bowl and use to coat the polenta cubes all over. Place on a foil-lined baking tray and grill for 5 minutes, turning once until lightly golden. Serve warm or cold with caramelised peppers.
