Preheat oven to 375 degrees F. Salt and pepper the chicken tenders and bake on wire rack placed on baking pan for ten minutes. Place the BBQ sauce in a medium bowl, toss the chicken tenders into the sauce, coating them completely. Place them back on the rack and cook for an additional ten minutes. Remove from oven, cool a few minutes on wire rack, chop and set aside. Assemble the wrap: place the tortillas flat on the counter. Top with the spinach, tomato, and cucumber, keeping the vegetables in the bottom third of the tortilla. Drizzle the dressing over the vegetables and distribute the chicken and cheese on top. Season with salt and pepper. Roll the tortilla up gently and firmly away from you, folding in the sides as you go (to make a closed burrito shape). Wrap tightly in wax paper and then slice in half. (This will help keep the wrap together during eating).
Wax paper helps keep the wrap secure and mess-free. For smaller children, use smaller tortillas and less filling. This recipe can be modified to be a pita instead.
