Preheat oven to 425° F. Place two Cooling Racks on Sheet Pan lined with Sheet Pan Liner; lightly brush racks with oil to prevent sticking.
In a large bowl, coat chicken with oil.
Place crumb mix in a resealable plastic bag. Add two chicken fillets at a time, shaking gently until evenly coated. Shake off excess. Place on racks, leaving a small space between each piece. Bake 15 min, or until cooked through.
Meanwhile, slice avocados and tomato. Spread 2 tbsp yogurt over each tortilla. Divide chopped lettuce, avocado slices, and tomato slices between tortillas. Once cooked, add chicken to tortillas. Roll tightly.
