Preheat the oven to gas 6, 200°C, fan 180°C. Arrange the pitta triangles on a baking tray, brush with a little olive oil, season, then bake for 6-7 minutes until golden. Set aside until needed.
Meanwhile, heat a griddle pan on the hob. Using a vegetable peeler, slice the courgettes lengthways into ribbons. Toss in a large bowl with 1tbsp of oil and some seasoning. Griddle the courgettes in batches, until lightly charred on both sides.
In a small bowl, combine the dressing ingredients and whisk with a little seasoning.
To serve, arrange the watercress on a serving platter and top with the pitta crisps, ripped mozzarella and courgettes. Drizzle over the dressing and garnish with the chilli flakes and some freshly ground black pepper.
