Is it safe or healthy to eat any greasy foods 3 days after a lower wisdom tooth extraction?

Safe but not healthy: You may eat anything that you can consume comfortably. Usually a soft diet is followed because your jaw is sore. You can eat greasy foods but they are generally not good for your health(heart). If nauseated from surgery, greasy and heavy foods may make you ill. Do drink extra water.

Carefully: Keep any food out of the socket area. If you lose the blood clot, you will get a dry socket and be in pain for a few weeks. Cut things up very small and chew on other side. Carefully rinse gently after eating. If you think it is a bad idea to do something -- it probably is ! good luck.
