    * 4 tablespoons olive oil

    * Juice of one lemon 
    * 1 cup shredded lettuce 
    * 1 red onion, sliced

PREPARATION:

    * Preheat the grill. Season the meat with 2 tablespoons olive oil, salt
      and pepper. Brush the pita bread with the remaining olive oil. Place 
      the meat on the grill and cook for 2 minutes on each side. Place the
      pita bread on the grill and cook for 2 minutes on each side. 
    * In a mixing bowl, mix the yogurt, cucumbers, and lemon juice together.
      Season with salt and pepper. Spread the cucumber sauce evenly into each
      pita bread. Divide the meat up between the pita breads. Garnish each
      sandwich with lettuce, onion and tomatoes. Makes 6 gyros
