Nothing says "toastie" like Dijon mayonnaise. And Jarlsberg®, of course!
Mix together the mayonnaise and Dijon mustard. Chop the parsley. Fry the bacon until crisp and golden. Spread the Dijon mayonnaise on the bread and top with Jarlsberg® cheese, bacon and parsley. Put the two slices of bread together. Fry the sandwich on both sides over a medium-high heat in a frying pan until the bread takes on a golden colour and the cheese has melted. Use plenty of butter in the pan. Serve with pickled gherkin and extra Dijon mayonnaise.
