Spread the hummus or mayonnaise over the tortilla. Top with ham, cheese, and lettuce.
Starting at one end, tightly roll the tortilla into a roll. Wrap the entire roll with plastic wrap and refrigerate overnight. If making this the morning of, skip this step and proceed with the recipe.
Pack the pinwheels for lunch:
When you're ready to pack, remove the plastic wrap and cut the roll into 1-inch pinwheels.
Add the pinwheels to a compartmentalized lunch container, keeping them separate from the veggies and fruit.
Close the container and pack it into a lunch bag with an ice pack.
