Warmth the oil in an expansive non-stick skillet. Include the leeks and 2 tbsp water, and cook for around 10 mins until exceptionally delicate. Include the bacon, turn up the warmth and broil until cooked.
In the interim, cook the pasta adhering to pack directions. Channel and hold a cup of the cooking water.
Spoon cheddar into the leek and bacon blend, including a portion of the saved cooking water. Season and mix delicately over a low warmth until softened. Hurl through the cooked pasta, including somewhat more cooking water, if necessary, to enable the sauce to coat the pasta.
