One possibility that may not work because it's a bit messy is an orange.
The sections are made up of little "juice vesicles" which are very visible
to the eye and contain only about a hundred cells.  Should be visible with
a hand lens.  Of course, the reason they're so big is the same reason
they're so messy -- huge vacuoles full of juice.  Any citrus should do as
well.
