Fire up the barbecue for kabobs – a welcome change from the ubiquitous burgers and hot dogs. Serve with a green salad.
Mix vinegar, oil, lemon juice, Worcestershire sauce, and spices for marinade. Pour marinade over pork cubes, place in sealable plastic bag, and refrigerate 4 to 24 hours, turning bag occasionally.
Remove meat from marinade and thread onto skewers. Grill over hot coals, basting with reserved marinade, for about 4 minutes on each side. Serve by pulling meat off skewers onto slices of bread.
