Note: A grown-up must supervise and help with preparation.
Method:
Preheat oven to 180°C/350°F/Gas Mark 4.
Using a small round cookie cutter, cut as many mini pizza bases as you can get from the naan bread.
Spread a thin layer of tomato puree over each naan circle, then place them all on a baking tray.
Sprinkle over the grated cheese then bake in the oven for 5-10 minutes until the cheese is melted and bubbling.
Whilst the pizzas are cooking, slice 4 of the olives in half for the spiders bodies. Slice the remaining olives in half, then cut each half into 4 legs so that you end up with 8 spider bodies and 8 legs for each of them.
As soon as the pizzas are cooked, remove from the oven and immediately top each on with an olive spider.
