Preheat your grill or grill pan over medium-high heat.
Season the chicken breast with salt and pepper. Grill for about 6-7 minutes per side or until fully cooked and juices run clear.
While the chicken is grilling, prepare the avocado dressing by blending the quarter avocado, Greek yogurt, lime juice, cilantro, salt, and pepper until smooth.
Thinly slice the tomato, red bell pepper, and cucumber. Tear the romaine lettuce into bite-sized pieces.
Once cooked, slice the grilled chicken into strips.
Lay the whole wheat wrap on a clean surface and layer the lettuce, cucumber, bell pepper, and tomato.
Place the grilled chicken strips on top, drizzle with creamy avocado dressing, and wrap tightly.
Serve immediately and enjoy your balanced, nutrient-rich meal.
