To make marinade, combine salad dressing, catsup, wine, Worcestershire sauce, salt and pepper. Cut steak into 1-1/2 inch cubes. Put steak cubes and raw shrimp in marinade and let stand in refrigerator 3 hours. Remove beef and shrimp from marinade; alternate 8 beef cubes and 8 shrimp on 6 skewers, using squares of bacon, slices of pepper and onion, and mushrooms between meats. Place skewers 4 to 6 inches abover medium heat on grill. Cook 8 to 10 minutes on each side, brushing with marinade occasionally. SOURCE: Southern Living Magazine,sometime in 1974.
