Place one flour tortilla flat on a clean work surface.
Spread approximately 2 tablespoons softened cream cheese evenly over the tortilla, leaving a small border around the edge.
Arrange a thin layer of sliced turkey over the cream cheese.
Place 2 thin slices of cheddar over the turkey.
Add a small amount of completely dry lettuce.
Starting from one side, roll the tortilla tightly into a compact log.
Repeat with the remaining tortillas and filling.
Wrap the tortilla rolls and refrigerate for approximately 15–20 minutes to firm.
Trim the uneven ends with a sharp knife.
Slice each roll into approximately 1-inch pinwheels.
Place 4–6 pinwheels into each lunch box.
Add strawberries, grapes, cucumber slices, crackers, or other preferred sides.
Keep refrigerated until packing and use an insulated lunch bag with a frozen ice pack when refrigeration is unavailable.
