Saute the onion in olive oil for 5-7 minutes so it starts to become caramelised. Add the garlic and tomato paste and cook for another minute.
Add the can of beans along with their liquid and use that to deglaze the pan. Stir through the harissa, oregano and cream and let simmer for another 5-10 minutes (depending on how much time you have).
While the beans are simmering, toast your bread.
Stir through the fresh lemon and serve topped with basil.
