- Step 1
Preheat oven to 200°C. Brush 2 baking trays with oil to lightly grease.
- Step 2
Place the sheets of puff pastry on a clean work surface. Fold the edges inward to create a 1cm-wide border. Evenly sprinkle 25g (1/4 cup) of the cheddar inside the border of the pastry squares. Distribute the mushrooms, tomatoes and olives evenly over pastry squares. Sprinkle with the remaining cheddar and season with black pepper.
- Step 3
Cook in preheated oven for 15 minutes, swapping the trays halfway through cooking, or until the pastry puffs and is golden brown underneath. Serve immediately.
Serves: 4 as a light meal. Feta-stuffed green olives are available in most supermarket delicatessens.
