Contains pork – recipe is for non-Muslims only
Soften onion and celery in pan with oil for 10 mins. Add bacon, then fry for 3 mins, until beginning to brown. Add garlic, then cook for 30 secs. Pour in tomatoes and stir through tomato purée, treacle or sugar and vinegar. Simmer over a high heat until thickened, between 5-10 mins, stirring often to make sure mixture doesn’t catch. Gently stir beans through, then cook for a further 2-3 mins on medium heat, until heated through. Meanwhile, make mash. Boil potatoes until tender, about 15 mins, then drain. Mash with milk, cheese and seasoning. Fill 2 small microwave-safe bowls three-quarters full with bean mixture. Add a generous dollop of mash to top, smooth over with a spoon. Chill when cool (or freeze for up to a month at this stage). Place small plate on top of dish, then microwave on High for 3 mins or until piping hot.
