Toad in the hole with red onions

Method

1. Preheat the oven to 220°C/fan200°C/gas 7. Sift the flour and salt into a bowl. Make a well in the centre, add the eggs and milk, and whisk to a smooth batter.
2. Heat 1 tablespoon oil in a large frying pan over a medium heat and add the sausages. Brown for 5 minutes, turning regularly, then set aside. Add the onions to the pan and cook for a further 8 minutes, adding the thyme halfway through. Set aside.
3. Pour the remaining oil into a medium ovenproof dish and heat in the oven for 5 minutes. Arrange the sausages and onions in the dish, then pour over the batter. Bake for 20-25 minutes, until puffed up and golden.
4. Meanwhile, put the frying pan back over a medium-high heat, sprinkle in the extra flour and stir for 30 seconds. Gradually whisk in the red wine, then the chicken stock. Bubble for about 5 minutes to reduce the gravy by half. Keep warm over a very low heat.
5. Serve the toad-in-the-hole with the hot gravy, a dollop of wholegrain mustard and some steamed greens, if you like.
