Rinse and drain the spinach leaves, set aside.
Pour the oil in a frying pan, add the spring onion and garlic slices and turn on the heat.
When they begin to turn brown, add the chilli and spinach leaves - a handful at a time, then stir. Add the lemon juice, cover with the lid and simmer for 2-3 minutes.
Put the prawns on top of the wilted spinach, cover with the lid and steam for 2-3 minutes, until the prawns have changed colour. If you’re using ready cooked prawns, just warm them through for a minute or so.
Take the pan off the heat, rest for a couple of minutes. Season to taste, then serve with paprika dusted on top.
