Step 1: Boil a pot of water with some salt and about a tblsp of olive oil. Add tagliatelle and cook as normal.
Step 2: Cut bacon up into small pieces (can literally be torn up using hands) Buy lean bacon if you can or make sure you take off extra fat.
Step 3: Fry the bacon in the bottom of a small pot (with some olive oil if you wish) until almost cooked then add sliced leeks.
Step 4: When leeks are soft, add all of the soft cheese, stir in and add some double cream until you reach desired consistency. Salt to taste.
Step 5: When your sauce is ready, add to drained pasta and serve. My friends love this and 4 people can eat for under a fiver!
