Cook the garlic with some oil and add courgette and salt. Cook it for a few minutes, but keep an eye as you want them to stay crunchy and not too soft.
In the meantime prepare the sauce: add all the sauce ingredients to a blender and blitz until you form a creamy sauce. Adjust salt to taste.
Add beans to your courgette and the. The sauce. Simmer.
To serve I have added: extra virgin olive oil, pepper, a sprinkle of fried onions and lemon zest.
