Wash fruit and veggies. On a flat surface, roll up the deli ham slices and cut into bite-sized pieces. Slice the cheese into squares.
Assemble
Place cheese and ham in one compartment. Put the rest of the items in different compartments. Keep dry ingredients like pretzels separate so they don't get soggy.
Pack for school
Refrigerate everything until ready to use and then pack in a lunch bag with an ice pack.
