This vibrant roasted cauliflower and radicchio salad is a masterclass in balancing textures and flavours. The star of the dish is the caramelised cauliflower, which brings a mellow sweetness that perfectly offsets the slightly bitter crunch of the purple radicchio and fresh romaine. Finished with a punchy shallot vinaigrette and a generous handful of flat-leaf parsley, it is a sophisticated vegan option that works beautifully as a substantial lunch or an elegant side dish.
Packed with plant-based nutrients, this colourful salad is particularly satisfying during the cooler months when brassicas are at their best.

How to make Roasted Cauliflower and Radicchio Salad
Put oven rack in middle position and preheat oven to 232°C.
Toss cauliflower with 1/4 cup oil, 1/2 teaspoons salt, and 1/8 teaspoons pepper in a large bowl. Spread in 1 layer in a shallow baking pan (1 inch deep) and roast, turning over with tongs halfway through roasting, until tender and golden brown, 25 to 30 minutes total. Cool in pan on a rack, then transfer to large bowl.
Whisk together vinegar, shallot, remaining 1/4 teaspoons salt, and remaining 1/8 teaspoons pepper in a small bowl, then add remaining 80ml oil in a slow stream, whisking until emulsified. Add half of dressing to cauliflower and toss to coat. Add cos, radicchio, parsley, half of nuts, and remaining dressing to cauliflower and toss to coat. Season with salt and pepper and sprinkle with remaining nuts.
