Preheat the oven to 220 degrees.

Wilt the spinach in a saucepan with 1 tbsp of the olive oil. When it is all wilted, take off the heat and leave to one side while you make the sauce.

Finely chop the ginger and garlic, then add to another saucepan with the remaining olive oil. Sizzle for 2 minutes, then add the cumin, coriander and garam masala. Cook for 1 more minute then add the tomato puree and 100ml water. Stir well, then add the sugar and a little salt. Remove from the heat.

Spread the tomato sauce over the top of each naan bread. Squeeze the spinach to remove any excess water, then dot it over the naans. Sprinkle over the chicken. Chop the paneer and add this too.

Bake in the oven for 10 minutes, or until the naans are crisp and the paneer is golden. Serve sprinkled with fresh coriander and with the yoghurt on the side for dipping.
