While pasta is cooking heat butter in a medium size skillet ( over medium heat) add leeks cook for 3 minutes ( keep those leeks moving) add salt and pepper.
Add cream and 1 tablespoon of lemon zest - mix and heat for 5 minutes

Add pasta to the chicken mixture and stir ( I mixed them together in the stockpot where I cooked the pasta)
