Wash and clean Swiss chard and set aside to drain. Cut steak in square pieces. Season with salt, pepper, parsley flakes and minced garlic. Wrap each piece of steak with 2 pieces of Swiss chard, criss crossed, roll and tie with household string. Lightly brown about 5 cloves of garlic in oil. Use a large roasting pan. Place rolled steak and chard in pan adding 3 cut ripe tomatoes on top. Simmer covered for about 1 hour. Uncover and cook another 15 minutes until excess water evaporates.
