Preheat the oven to 220C/425F/Gas 7.
To make the base, mix the flour, yoghurt, water and seasoning together in a bowl to make a dough. Using floured hands, shape the dough into a ball and roll out on a floured surface to form a thin circle.
Place the dough base in a pan and dry-fry for 2-3 minutes on each side, until lightly coloured, then transfer the base onto a baking sheet.
Spread the tomato purée on top of the base and scatter with the cherry tomatoes.
Sprinkle with garlic and drizzle with oil. Arrange the chopped pepper pieces and the salami pieces on top.
Scatter the grated halloumi cheese on top, then place in the oven to bake for 8-10 minutes, until the cheese has melted and is golden.
Remove from the oven and serve.
