Citrus-Ginger Flat Iron Steak

• 1/4 cup fresh lime juice
• 3 tablespoons fresh lemon juice
• 1/3 cup fresh grapefruit juice
• 2 tablespoons rice vinegar
• 1 tablespoon olive oil
• 1 teaspoon soy sauce
• 2 teaspoons chili garlic sauce
• 2 teaspoons honey
• 1 1/2 teaspoons minced fresh ginger root
• 1 teaspoon garlic salt
• 1/2 teaspoon black pepper
• 1 pinch ground cinnamon
• 1 (1 pound) flat iron steak

1. Whisk together lime juice, lemon juice, grapefruit juice, rice vinegar, olive oil, soy sauce, chili garlic sauce, and honey in a bowl until the honey has dissolved. Season with ginger, garlic salt, pepper, and cinnamon; whisk until blended. Place the flat iron steak into a resealable plastic bag, and pour the marinade overtop. Squeeze out the excess air, seal, and marinate in the refrigerator 1 1/2 hours. Do not marinate much longer than this, as the citrus juice will "cook" the beef.
2. Preheat an outdoor grill for medium-high heat.
3. Remove flat iron from the marinade, and discard the remaining marinade. Cook on preheated grill until the steak has attained your desired degree of doneness, about 2 minutes per side for medium-rare. Place steak onto a plate, set aside, and allow to rest for 3 to 4 minutes before slicing.
