Well there is the right way and the easy way. The easy way first because, well just because. Take the wheel off and turn it so it is sitting straight and tighten the nut. Looks good but things under the car are not right.
The right way to fix this problem is to have the car's front tires on turntables and then adjust the tie-rod ends. But you would want this done at an alignment shop because they have all of the gauges to set it correctly. Just be sure to tell them to "center the wheel".
