Sweet vs salty is the key balance here, the onions and pear stop the Roquefort overpowering everything. | Give the potatoes space on the tray or they will steam instead of crisp. | If blue cheese feels strong for the kids, mix it half-and-half with cream cheese. | Want extra depth? Add a tiny splash of Worcestershire sauce to the onions while they cook. | Cold burger sliced into the salad the next day works brilliantly. | Extra potatoes can be reheated in a hot pan and topped with fried eggs for breakfast. | The Roquefort sauce is excellent stirred through warm pasta or spread on toast with tomatoes.
