In a bowl, combine soy sauce, oil, brown sugar, garlic, ginger and salt; mix well. Pour half of the marinade into a large resealable plastic bag or shallow glass container; add beef and turn to coat. Seal or cover; refrigerate for 4 to 8 hours, turning occasionally. Cover and refrigerate remaining marinade. Drain meat; discard marinade. On metal or soaked bamboo skewers, alternate meat, mushrooms, green pepper, onion and cherry tomatoes; leaving 1/4 inch between each. Grill, uncovered, over medium heat for 3 minutes on each side. Baste with reserved marinade. Continue turning and basting for 8 to 10 minutes or until meat reaches desired doneness. Serve meat and vegetables over rice if desired.

Yield: 6 Servings.
