Spread pesto evenly over 4 bread slices and mayo over the remaining 4 slices.
Top the pesto slices of bread with turkey, cheese, lettuce, a pinch of sprouts, and then the mayo slices, forming 4 sandwiches. Cut into halves or quarters if desired.
Peel carrots and cut into sticks; slice pears into wedges.
Serve sandwiches with carrots and pears on the side.
