Heat the oven to 200C. Put the capsicums on a tray and roast for 30-35 minutes, turning occasionally, until they are cooked, and the skin is blackened.
Transfer to a bowl, cover with clingfilm.
Allow to cool completely. Peel and discard the inner seeds.
Blitz in a food processor but allow the capsicum to have some texture, you don’t want a smooth looking paste.
Add the breadcrumbs, lemon juice, molasses, cumin, chili and garlic. Blitz a few more times.
Stir through the walnuts, pinch of salt and the olive oil. Spoon the dip into a shallow bowl, drizzle with more olive oil and serve at room temperature.
