For the Chicken:
Chop the chicken breasts into 1-inch pieces.
Marinate the chicken with all the marinade ingredients and store in fridge for 1 hour.
Grill the chicken on each side for 1-2 minutes or until the chicken is done.
For the Herb Roasted Potatoes:
Preheat the oven to 200C/400F
Cut the potatoes into wedges or cubes. No need to peel them.
In a roasting pan add all the ingredients for the herb roasted potatoes and mix well.
Bake uncovered for 40-50 mins, turning the potatoes in between so that they cook evenly and form a nice crust. You can add more water (about 1/4 cup) if you feel the liquid is drying up before the potatoes are cooked through.
For the Tzatziki Sauce:
Mix all the ingredients for the tzatziki sauce and refrigerate until it's time to serve.
Assembling the Wraps:
Fill each pita bread with desired amount of chicken, salad and tzatziki sauce. Serve with herb roasted potatoes.
