Preheat the oven to 200C and line a baking tray. Toss the cubed pumpkin with a little olive oil and paprika. Roast for 30 minutes then set aside until ready to serve.
Prepare the remaining salad ingredients except for the dressing and toss together in a large bowl with the roasted pumpkin.
Whisk the dressing ingredients and taste for salt and pepper and more lemon. Drizzle over the combined salad.
