This is an easy one. Boil your favourite noodle shapes in salted water according to the package directions. Drain through a colander then return the noodles to the pan and stir through a knob of butter while the noodles are still hot. I like to use a ridged noodle shape so that the butter clings more easily to the noodles. Serve them hot alongside the salmon and spoon the asparagus and cheesy sauce on top of the noodles.
