Add the paste ingredients to a blender and blend until smooth.
Transfer the paste to a large pan and cook for 5–10 minutes, until it reduces down into a thick paste.
Add half of the coconut milk, along with the chickpeas and vegetables. Cook until the coconut milk has reduced.
Now add the remaining coconut milk, salt to taste, and the tuna.
Simmer the curry until the tuna is piping hot, then serve over rice.
To finish, I love adding chopped chillies, fresh coriander leaves, and a squeeze of lime.
