Heat the oil in a frying pan set over a low heat and fry the onion with a pinch of salt for 10 mins. Add the garlic and chilli flakes, and fry for 2 mins more. Tip in the beans, thyme and stock, bring to a simmer and cook for 15 mins, or until the beans have broken down a little. Stir in the crème fraîche and lemon zest. Season to taste.

To make the salsa verde, put the parsley, hazelnuts, garlic, capers, vinegar and oil in a pestle and mortar and crush everything together – this will take about 5 mins. Alternatively, blitz in a food processor until combined but not smooth. Transfer to a bowl and season to taste.

Light the barbecue and wait for the flames to die down. Cut the aubergines in half lengthways and score the cut side in a diamond pattern using the tip of a knife. Rub with some oil, then put directly on the grill and cook for 7-10 mins on each side, or until charred and soft. Alternatively, cook under a grill (see tip, below). Top the cooked aubergines with the bean ragu and salsa verde, then scatter over the toasted almonds and serve with the lemon wedges on the side.
