Try a Chinese style marinade, it's lovely with pork or chicken. I can't give quantities because I'm a sort of "just-chuck-it-in-and-see-what-happens" type of cook, but my marinade usually contains a mix of crushed garlic, grated ginger, soy sauce, lemon juice, five spice powder, honey, sunflower oil, and. bit of finely chopped chilli. Mix it all together and put in either a plastic bag or a plastic dish with a lid on. Add the sliced pork and mix thoroughly till everything's coated. Leave for as long as possible before cooking. Delicious.
