In a medium sized bowl combine the french dressing, ketchup, soy sauce, garlic powder and soy sauce. Mix together until well combined.
Place meat in a shallow pan. Pour marinade over meat. Marinate overnight or at least 3 hours. Turn meat over during the marinating time.
Before grilling remove meat from the marinate brushing off excess sauce.
Depending on the thickness (or depending on how you like your meat cooked), here's a good rule of thumb for cooking steaks: Place the steaks on the grill and cook until golden brown and slightly charred, 4 to 5 minutes. Turn the steaks over and continue to grill 3 to 5 minutes for medium-rare (an internal temperature of 135 degrees F), 5 to 7 minutes for medium (140 degrees F) or 8 to 10 minutes for medium-well (150 degrees F).
