Greek Seasoned Steak Sandwiches

Found this recipe in the August 2013 edition of Cooking Light and gave it a shot. Not bad. :) We used the leftover meat and sauce on a salad the next day. 

Ingredients:

• 3 tablespoons red wine vinegar, divided
• 4 teaspoons extra-virgin olive oil, divided
• 1 tablespoon minced garlic
• 1 teaspoon dried oregano
• 12 ounces flank steak, trimmed
• 1/2 teaspoon kosher salt, divided
• 3/8 teaspoon freshly ground black pepper, divided
• Cooking spray
• 2 tablespoons plain fat-free Greek yogurt 
• 1/4 teaspoon Dijon mustard
• 4 (6-inch) whole-wheat pitas
• 4 romaine lettuce leaves
• 4 thin red onion slices
• 1 cucumber, peeled and thinly sliced 
• 1 tomato, cut into 8 slices 

Preparation

1. 1. Combine 2 tablespoons vinegar, 1 teaspoon oil, garlic, and oregano in a large zip-top plastic bag. Add steak to bag; seal. Let stand at room temperature 20 minutes, turning once.
2. 2. Heat a grill pan over medium-high heat. Remove steak from bag; discard marinade. Sprinkle 3/8 teaspoon salt and 1/4 teaspoon pepper evenly over both sides of steak. Coat pan with cooking spray. Place steak in pan; grill 5 minutes on each side or until desired degree of doneness. Remove steak from pan; let stand 10 minutes. Cut steak across the grain into thin slices.
3. 3. Combine remaining 1 tablespoon vinegar, 1 tablespoon oil, 1/8 teaspoon salt, 1/8 teaspoon pepper, yogurt, and mustard in a bowl, stirring with a whisk.
4. 4. Cut off one-third of each pita; discard or reserve for another use. Arrange 1 lettuce leaf, 1 onion slice, one-fourth of cucumber slices, 2 tomato slices, and one-fourth of steak in each pita; top each sandwich with 1 tablespoon yogurt mixture.
