In a mixing bowl, combine olive oil, garlic powder, paprika, salt, and pepper.

Add the chicken breasts to the marinade, ensuring they are well-coated. Let them sit for at least 15 minutes.

Heat your grill to medium-high.

Place the marinated chicken on the grill and cook for about 6-7 minutes on each side.

Once cooked, remove the chicken from the grill and let it rest for 5 minutes.

Using a sharp knife, slice the chicken into strips.

On each tortilla, layer the shredded lettuce, diced tomatoes, chicken strips, cheese, and drizzle with ranch dressing.

Wrap the tortillas tightly around the filling and slice in half.
