Pretty vague, by "kick it up" do you mean like some heat, you could add some cayenne or chipotle. Or are you looking for something more savory......a whole host of various rubs out there. Combo of sweet and savory........again, the rubs.
A pork loin with salt, pepper, garlic, rosemary and some EVOO, grills up nicely, and is very tasty.
Just depends on what you are looking for.
