Serves 4 or 5
1 head of lettuce
3 slices of bacon

Remove the softer outer leaves. Cut of break away the lettuce from the stem and reassemble the head loosely in a bowl. Fry the bacon, then remove the bacon and most of the fat. Leave about 2 tablespoons.
Add the sugar and vinegar, bring to a boil, swishing the pan around to stir.
Pour the boiling mixture over the lettuce in the bowl. Crumble up the bacon and scatter on the top and serve piping hot
