Chicken Marinade

I thought it was time I start using marinades so I found this one on Allrecipes.com that sounds good. I didn't measure and it turned out great. I also omitted the liquid smoke because we didn't have any.

Ingredients

• 2/3 cup olive oil
• 2/3 cup reduced-sodium soy sauce (I used a little dark soy for color)
  
• 1/4 cup lemon juice
• 2 tablespoons liquid smoke flavoring (Didn't have any)
  
• 2 tablespoons spicy brown mustard (Didn't have any)
  
• 2 teaspoons ground black pepper (Used white pepper instead)
  
• 2 teaspoons garlic powder
• 4 skinless, boneless chicken breast halves

Directions

1. In a large bowl, mix the olive oil, soy sauce, lemon juice, liquid smoke, mustard, pepper, and garlic powder. Place chicken in the bowl, and coat with the marinade. Cover, and allow chicken to marinate a maximum of 4 hours in the refrigerator. (I marinade for 30 mins)
   
2. Preheat the grill for high heat.
3. Oil grill grate. Discard marinade, and place chicken on grate. Cook 6 to 8 minutes on each side, until juices run clear.
