This is sunshine soup.  It’s the the kind of soup that will cheer you up in the dead of winter.  In fact, just peeling and dicing the beets, exposing their brilliantly yellow flesh, put a great big smile on a my face.  There’s just something about that color – sunny, warm, cheerful – that will wash away all the gray, stuck-indoors feelings of a frigid January.  Smokey cumin and spicy red pepper flakes evoke the cradling heat of a dry Mexican desert while a burst of lime leaves you resting on the white beaches of a tropical getaway.  Daydream.  Forget about winter for just a moment and brighten your day with this sunshine soup!
