Follow these simple steps to create your Southwest Chicken Wrap:

1. Marinate the Chicken: In a bowl, mix olive oil, salt, and pepper. Add the chicken breast and let it marinate for 10 minutes.
2. Cook the Chicken: Heat a skillet over medium heat. Cook the marinated chicken for about 6-7 minutes on each side or until fully cooked. The internal temperature should reach 165°F (75°C).
3. Slice the Chicken: Once cooked, remove the chicken from the skillet and let it rest for a few minutes. Then, slice it into thin strips.
4. Prepare the Tortillas: Warm the tortillas in a dry skillet or microwave for just a few seconds to make them flexible.
5. Layer the Wrap: On each tortilla, place a generous handful of mixed greens, followed by the sliced chicken, diced tomatoes, and shredded cheese.
6. Add Dressing: Drizzle your preferred dressing over the fillings. Ranch is a classic choice, but feel free to use a southwest style dressing for extra flair.
7. Roll it Up: Carefully fold in the sides of the tortilla and roll it tightly from the bottom to the top, securing all the fillings inside.
8. Serve: Cut the wrap in half if desired and enjoy!
