Step 1

Heat the oven to 200C/180C fan/gas Toss the red onion, potatoes, artichokes, tomatoes, spring onions, sausages, fennel seeds and lemon wedges together in a baking tray or 20 x 20cm baking dish. Drizzle over the oil and season to taste (you won’t need a lot of salt, as the sausages can be quite salty).

Step 2

Roast for 20 mins, then add the beans and stock. Roast for 35 mins more, then remove from the oven, swirl through the pesto and serve with crusty bread, if you like.
