Heat the ghee or oil in a heavy-based skillet over a moderate heat. Add the onion and bacon and saute for 5 minutes. Add the sage leaves, paprika and garlic, sauteing briefly to release the flavours. Add the beans and tomato passata. Cook for 5 minutes until bubbling. Remove from the heat and serve immediately with winter greens and half an avocado. So simple and delicious, enjoy!
