1. In a large bowl, blend the soy sauce, olive oil, water, mustard, garlic, and pepper. Place the beef tri tip in the marinade. Cover, and marinate in the refrigerator at least 4 hours. I make it the night before and marinate it for 24 hours.
2. Preheat an outdoor grill for high heat, and lightly oil grate.
3. Grill the beef 5 minutes per side, or to desired doneness. Discard remaining marinade.
