White bean, courgette & fennel stew with sausage crumb

Put a heavy-based saucepan over a medium heat and cook the sausage crumb until crisp. Use a slotted spoon to transfer it to kitchen paper, keeping as much fat in the pan as possible. Add the courgettes to the pan, in batches, and fry for 1-2 minutes on each side, until golden. Transfer to a plate and set aside.

Tip the fennel, onion and garlic into the pan with a pinch of salt and fry, stirring occasionally, for 5 minutes, or until softened. Pour in the wine and let it bubble away until reduced by ½, then add the courgette and ½ the sausage crumb back to the pan. Dissolve the stock cube in 300ml just-boiled water and pour it in, along with the butter beans. Simmer for 5 minutes. Season and stir through the parsley

Mix the crème fraîche and mustard together. Divide the stew between 4 bowls and top with a spoonful of mustardy crème fraîche, the reserved sausage crumb, fennel fronds and a good grind of black pepper.
