Slice the chicken breast into thin strips and season evenly with half of the garlic powder, onion powder, sea salt, and black pepper.
Heat the olive oil in a non-stick skillet over medium-high heat.
Add the chicken strips to the skillet and sear for 5-7 minutes, turning occasionally until golden brown and cooked through.
In a small bowl, whisk together the Greek yogurt, dried dill, lemon juice, and the remaining garlic powder, onion powder, salt, and pepper to create the ranch dressing.
Lay the tortilla flat and spread the yogurt ranch across the center.
Top with the chopped romaine lettuce, halved cherry tomatoes, and the warm crispy chicken.
Fold in the sides of the tortilla and roll tightly to secure the wrap.
Optional: Place the wrap back in the hot skillet for 30 seconds per side to toast the exterior for extra crunch.
