BLACK BEAN BURGER WITH BABA GHANOUSH, GRILLED SPRING ONIONS AND ROASTED PINE NUTS

Uh-oh! We're unable to calculate nutrition for this recipe because some ingredients aren't recognized.

Step 1

Enough for 6 burgers 100 ml (3½ fl oz/scant ½ cup) olive oil sea salt and freshly ground black pepper 6 spring onions (scallions)

Step 2

1. Pour the oil into a ziplock bag big enough to accommodate the spring onions. Sprinkle with salt and pepper. Put the bag next to the barbecue so it is close at hand.

Step 3

2. Light the barbecue. Lay the spring onions on the grid while the charcoal is still actively flaming. Cook the onions all over so the surface gets a little burnt.

Step 4

3. Using tongs, transfer the spring onions to the ziplock bag. Seal the bag and shake it so the oil covers all the onions. Leave them in the bag for about 20 minutes so they steam in their own heat.

Step 5

1. Rinse the beans in cold water and drain in a colander.

Step 6

2. Heat a little oil in a frying pan (skillet) and fry the onions over a fairly high heat until they have developed some colour and are on the verge of burning.

Step 7

3. Reduce the heat, add the chilli and paprika powders and stir. Stir in the BBQ sauce and remove the frying pan from the heat.

Step 8

4. Roast the walnuts as described on Dry-Roasted Walnuts.

Step 9

5. Chop the walnuts and put them in a bowl together with the beans, coriander, rice, panko breadcrumbs and a pinch of salt. Mix the ingredients together with a potato masher (the beans should only be lightly mashed). Add the onion mixture and stir so that everything is well combined.

Step 10

6. Take a handful of mixture at a time and shape into 6 round patties, either by hand or using a food ring. Put the patties on a large plate and cover with cling film (plastic wrap). Put in the fridge for at least an hour, preferably longer, so that they will hold together better when you fry them.

Step 11

7. Preheat the oven to 180°C (350°F/Gas 4).

Step 12

8. Heat a few tablespoons of oil in a frying pan. Fry both sides of the patties over a medium heat for a few minutes. Transfer the patties to an ovenproof dish and bake them in the oven for 5–10 minutes.

Step 13

9. Butter the buns on the cut surface and fry them quickly in a frying pan or grill (broil) them in the oven.

Step 14

10. Place a patty on the bottom of each bun. Add a generous dollop of baba ghanoush, follow with some grilled spring onions and top with toasted pine nuts, parsley sprigs and lemon zest.
