Step 1

Make the Romesco Sauce: In a blender, combine the red peppers, tomato paste, water, vinegar, chickpeas, hazelnuts, almonds, garlic, paprika, olive oil, and a pinch of salt and pepper. Blend until smooth. Season to taste.

Step 2

Preheat the oven to 400°F. Cut two 1-inch thick slices from the cauliflower, keeping the core intact. Heat the oil in a large cast iron pan. Place the cauliflower steaks into the pan and gently press them down. Lightly brush the top of the steaks with a little more oil, and season with salt and pepper. Sear for 2 minutes per side, or until golden brown, then transfer to the oven and roast for 15 minutes or until the cauliflower is tender but firm.

Step 3

Spread two plates with romesco sauce and top each with a cauliflower steak. Sprinkle with the chopped parsley, pine nuts, golden raisins, and lemon zest. Season with salt and pepper to taste.

Step 4

Store extra romesco sauce in the fridge for up to 4 days. Slather it on sandwiches or use as a veggie dip.
