Wilt the spinach in a large shallow pan over a medium heat with a splash of water. Remove from the pan and squeeze out all the liquid. Set aside.
In the same pan, gently sweat the spring onions, peppers and garlic in the oil for a few minutes. Stir through the chilli, cumin, smoked paprika and coriander, and then add the spinach. Season with salt and pepper and mix well.
