Lay the tortilla on a clean work surface. Add the protein to the center of each tortilla. Add the remaining vegetables and other ingredients along with a drizzle of sauce, if included. Fold the wrap over the ingredients and pull back, pressing slightly to ensure a tight roll. Continue to roll to the end. Before finishing rolling, add a small spread of butter, mayonnaise of sauce to the last inch or so of the tortilla wrap to act and a 'glue'. Roll to seal. Tuck in the ends of the wrap on one end, or both ends, as you would fold a box lid to keep the ingredients in the wrap. Slice in half as you would a sub sandwich.
