Sausages with onion and mustard gravy

Method

• Step 1
  Preheat oven to 100°C. Heat a large frying pan over medium heat. Add the sausages and cook, turning occasionally, for 8 minutes or until brown all over and cooked through. Transfer to an oven tray and place in the oven to keep warm.
• Step 2
  Meanwhile, to make the mustard gravy, add the butter to the frying pan over medium-low heat. Add the onion and garlic and cook, stirring occasionally, for 15 minutes or until onion is soft and caramelised. Add the sugar and vinegar and cook, stirring, for 2 minutes or until well combined. Add the flour and stir to combine. Add the wine and bring to the boil. Add the beef stock and bring to the boil. Cook, stirring, for 2-3 minutes or until the sauce boils and thickens. Add the wholegrain and Dijon mustard and stir to combine. Remove from heat.
• Step 3
  Spoon mashed potato among serving plates. Top with sausages. Pour over the onion gravy and serve immediately with steamed peas, if desired.
