Place the pork steaks in a wide container so that they are in a single layer.
Mix the rest of the ingredients together. Pour the marinade over the pork steaks. Cover and keep in the fridge for several hours.
Twenty minutes before meal time, take the pork steaks out of the fridge and grill (stovetop grill, turbo broiler or convection oven). Depending on the size of the steaks, cooking would be anywhere from 15 to 20 minutes.
You may want to do something with the marinade while the steaks cook. Pour the marinade into a small pan, bring to the boil, cover and simmer until reduced to about half. You can serve this as a dipping sauce and it should go well with the pork.
While the pork steaks cook, make the asparagus fried rice.
