Method
- 1
Heat the oven to 200°C (180°C fan). Put the potatoes in a large roasting tin with 2 tbsp of the oil, the rosemary and a good pinch of pepper. Toss well.
- 2
Roast the potatoes for 15 minutes, until the edges just start to colour.
15 min - 3
Add the sausages, onion wedges and garlic to the tin. Drizzle with the rest of the oil and turn everything over so it is coated.
- 4
Roast for 25 minutes, turning once halfway. The sausages should be golden and the onions soft with dark edges.
25 min - 5
Add the tomatoes and the vinegar and roast for 10 minutes more, until the tomatoes split and smell sweet.
10 min - 6
Check a sausage is cooked through with no pink inside. Squeeze the garlic out of its skins if you like and serve straight from the tin.
