Spread a thin layer of your favorite condiment over the tortilla. Layer the lettuce or spinach, tomato, corn, ham, and cheese over the center.
Roll
Fold in the sides and roll the tortilla tightly, tucking the filling inside as you go. Slice in half.
Pack for lunch
Place the wrap in a hard lunch container and keep sides in separate compartments. Refrigerate until ready to pack in an insulated lunch bag with an ice pack.
