Pork Loin Chops with Red Wine Sauce

Lean pork can be rather dry on the grill.  On the other hand, it is a very healthy meal and I enjoy it.  So I have come to experiment with many marinades that make it tastier.  Here is my next one:

4-6 pork loin chops each about 2-3 inches thick
Marinade:
2 cups soy sauce
2 cups red wine

For Wine Sauce
marinade left over from meat
2 large sweet onions
1 tablespoon olive oil

Place the pork chops in a deep dish and cover with marinade.  Let the meat marinade about 2 hours.  Heat the grill to high heat and place the pork on it.  Cook until preferred temperature -- I cook it at least 10 minutes turning a couple of times and basting with marinade (I reserve about 1/2 cup for this, the rest is used for the wine sauce).
In the mean time slice the onions in thin slivers and place with oil in a large sauce pan and fry till onions are translucent.  Add the marinade left from the meat and simmer until sauce reduces to about 1/2 the amount.

Place the wine sauce in a bowl.  Serve the pork with your favorite side dish and / or salad and wine and onion sauce
