Step 1First, preheat the oven to 200 °C/ 400 °F (fan assisted), or 220 °C/ 425 °F (conventional).
Step 2Prepare the asparagus by cutting the woody ends off (250 g of asparagus in our recipe counts after cutting the ends off). Wash and deseed the bell pepper and slice it in small stripes. Peel and finely chop the shallot and spring onion.
