Bar-B-Q'd shrimp on a grill!  So good.  Here's a recipe that I love:  In a bowl, mix lemon juice, onions, parsley, olive oil, salt and pepper.  Throw in the shrimp (uncooked) for a few hours.  Put them on a skewer and grill them.  Don't overcook or they'll be rubbery.  Serve with good bread and a salad.
