This question was provoked by my latest shot of Indie for my 52 weeks of Indie project, but I generally shoot into the sun whenever I can. My shots also turn out pale because the sun naturally washes everything out, but you can easily bring back the detail and add contrast by using curves with your editing software of choice (mine is Aperture). Bring the curve down to beef up those midtones, then play around with it until you get the look you desire.
