In a closed bag or bowl, mix together all ingredients (I used low sodium soya sauce so I add a little salt) except the steaks. Once ingredients are mixed well, add the steaks and turn to cover well with marinade.
Place bag in fridge and leave over night (turning a couple of times).
Pre-heat BBQ, Grill or Pan Grill, remove steaks from bag and place on hot grill, turn and cook until desired doneness. Serve immediately. Enjoy!
