Easy way these days is the AAV -- air-admittance valve.

high as possible under counter) then pipe down from 45 under floor and up a wall and out the roof. You could pipe up to a 90 pointed horizontal then to a 90 pointed down pipe from there under floor over to wall and up. If you tie into an existing vent you must make your connection 6" above flood rim of sink ( top of sink)
