Lay the spinach wrap flat on a cutting board. Spread the soft cheese evenly in the center, leaving the edges clean so the wrap rolls tightly.
Add the spring mix greens on top of the cheese. Spoon the chopped rotisserie chicken over the greens, then sprinkle on the sun-dried tomatoes. Drizzle the pesto over the chicken and finish with crumbled feta.
Fold the sides inward, then roll from the bottom up to create a firm, compact wrap that holds the fillings in place.
Cut the wrap in half with a serrated knife. Enjoy immediately, or wrap tightly and refrigerate for later.
