Heat the oil in a large, lidded pan over a medium heat and fry the sausages until browned. Reduce the heat to low-medium, add the onions and carrots, and cook gently for 5 mins until soft.

Add the garlic and dried herbs, then cook for 1 min. Stir in the chopped tomatoes, stock cube, honey and mustard. Turn up the heat to medium and bring to the boil. Reduce the heat to a simmer and cook for 30-40 mins, stirring now and then, until the carrots are tender and the sauce has reduced a little.

Around 5 mins before serving, add the spinach, in batches if necessary. Cover and cook for 5 mins, until wilted. Season with salt and pepper, and serve with mashed potato, if you like.
