In a large baking dish place the soy sauce, oil, garlic, mustard, honey, onions, black pepper and parsley. Mix and then add the beef, mix and cover. Refrigerate for at least one hour.

If using wooden skewers soak them for 30 minutes. Metal skewers do not need this step. Put 4 pieces of beef on each skewer. But let the marinade drip back into the dish. Reserve the marinade.

Place on grill and grill for about 10 minutes. Brush the meat several times with the marinade. To check to see if the meat is grilled to your liking, remove one piece of beef and cut into it. If it needs a few minutes more, continue grilling. When done, remove from grill and let the beef rest for several minutes. This allows the juices to remain in the beef and not ooze out if you cut it immediately. Garnish and serve with the grilled veggies of your choice.
