Cook 160 g Spaghetti according to the packet instructions.
Heat 1 teaspoon Olive oil in a large pan and cook 50 g Bacon. Once cooked, chop into small pieces and set aside.
Whisk 1 Egg in a bowl and then add 50 g Parmesan and 3 tablespoon 0% Fat Free Greek yogurt. Mix well.
Once the spaghetti is cooked, drain (reserving some pasta water) and then put it into the pan with the bacon. Add the egg mixture to the spaghetti, stir briskly, so the egg does not scramble.
Slowly add 80 ml Reserved pasta water a little at a time until the sauce is silky and smooth. You may not need all of the water. Mix gently to coat all of the cooked pasta.
Serve with chopped basil and a little grated parmesan.
Notes
Use warm, not boiling, pasta water to control sauce texture.
Grate your own Parmesan for smoother melting.
Full-fat Greek yogurt gives the creamiest result.
Taste and season with salt and black pepper if needed.
If you are going to reheat this, then do it on the stove top rather than in the microwave.
