1: Peel, rinse and chop 250 g onion. Melt 20 g butter in a medium-sized saucepan. then add the chopped onions, salt and pepper and cook for 5 minutes, stirring from time to time.
2: Pour 250 ml red wine into the pan and stir well.
4: Cut 200 g belly (streaky) bacon into small pieces and pan fry lightly. Set aside.
5: Slice 200 g cooked potatoes and fry on both sides in the same pan as you used for the bacon. Ideally, you should not add any more fat and just use what has come out of the bacon. If there isn't enough, use a little oil.
