1In a bowl, mix the plain yogurt, tandoori spice mix, and lemon juice to create a marinade.
Cut the chicken breast into strips and coat them with the marinade. Let it sit for at least 30 minutes.
Preheat a grill or skillet over medium heat. Cook the marinated chicken strips until fully cooked, about 5-7 minutes on each side.
While the chicken is cooking, slice the red onion and bell pepper into thin strips.
Once the chicken is cooked, warm the whole wheat tortillas on a pan or in the microwave.
To assemble the wraps, place a layer of lettuce on each tortilla, followed by the cooked chicken strips, sliced red onion, and bell pepper.
Roll up the tortillas tightly to form wraps. Serve immediately and enjoy your Tandoori Chicken Wraps.
