Chop the onion and leek and grate the garlic.
In a wide pan, on a medium heat, add the olive oil, onion and leek along with a pinch of salt and sauté until translucent.
Add the grated garlic and sauté for a minute, before you add the beans.
Add a generous pinch of salt and pepper, the pesto and give it a good stir.
Add the milk, along with the nutritional yeast and all the spices and herbs, stir it again and start adding the water bit by bit.
Finish with some lemon zest and juice.
Toast your bread, I used pitta, add a generous spread of hummus on top, then add some of the pesto beans on top, a drizzle of olive oil and some pickled red onions.
