Teriyaki Pork Chops

This is a nice way to enjoy some tender and delicious pork chops on the grill.  The marinade is very simple, but perfect for a very nice combination of flavors.  Enjoy!
-1 garlic clove, pressed
-1/4 cup vegetable oil
-1/4 cup soy sauce
-3 Tbs ketchup
-1 Tbs distilled white vinegar
-1/2 tsp pepper
-4-5 pork chops
In a large ziplock bag, combine all ingredients, except for the chops.  Mix well, then add the pork shops.  Move around so that they're all evenly coated.  Refrigerate for about 4 hours, flipping the bag over every hour or so.
Heat up the grill, remove the chops from the marinade (discard the marinade) and cook to your desired doneness.  Enjoy!
