Calories 286 kcal


  • 1 head (1¾ lbs) cauliflower
  • 4 cloves garlic
  • oz sourdough bread
  • oz blanched almonds
  • 16 oz jarred roasted red peppers


  • Preheat the oven to 350°F. Trim away just the tatty outer leaves and the end of the stalk from the cauliflower, then halve, slice into 1¼-inch wedges and sit them in a roasting pan. Toss with a little olive oil, red wine vinegar, sea salt and black pepper, and roast for 35 minutes, or until beautifully golden and tender. Meanwhile, peel the garlic, tear the bread into small chunks, and place on a roasting pan with the almonds. Place in the oven when the cauliflower has just 15 minutes to go.
  • When the time’s up, remove the pans from the oven. Reserve a handful of almonds, then place the rest in a blender with the garlic and toasted bread, drain and add the peppers, 2 tbsp of olive oil and a swig of red wine vinegar, and whiz until silky-smooth. Loosen with a splash of water, if needed, then taste and season to perfection. Pour onto a serving plate, sit the cauliflower on top, then bash or chop the reserved almonds and sprinkle over, to serve.
