Chorizo & savoy cabbage rigatoni
Use Savoy cabbage in this chorizo pasta dish for its slightly bitter edge. Curly kale, chopped spring greens or spinach would also work well
Scatter the pancetta into a deep flameproof casserole dish and cook on a medium heat for 5-6 mins until crispy and releasing its fat. Remove from the pan using a slotted spoon, leaving any fat behind. Pour in the oil, then tip in the onion, celery and carrot. Cook for 12-15 mins until turning golden. Stir in the garlic and cook for 1 min more.
Pour in the beans, chicken stock and parmesan rind (if using). Cook for 15 mins on a medium heat, then stir in the cavolo nero and cooked pancetta for a final 5 mins. Stir in the sherry vinegar and season.
Divide between four bowls and sprinkle with chives to serve.
