A creamy cucumber-yogurt sauce and marinated chicken are stuffed into pitas for a hearty lunch or quick dinner in under 30 minutes.
1. Cut each chicken breast horizontally into 2 thin cutlets. In a large bowl, toss with ¼ cup (4 tbsp) Italian dressing until well coated. Refrigerate 15 min.
2. Meanwhile, use a box grater to coarsely grate the cucumbers into a medium bowl. Stir in the yogurt and remaining 3 tbsp Italian dressing. Season with salt and pepper to taste. Thinly slice the red onion and tomatoes.
3. Coat a large grill pan with cooking spray. Heat on medium-high. Add chicken to pan and cook 4–5 min. per side, until cooked through.
4. Lightly toast the pitas. Spread the cucumber-yogurt sauce inside the pitas. Chop the chicken and add to pitas, along with tomatoes, romaine, and red onion.
