Here's one I found a while ago, but I haven't actually tried it yet, so beware.
1 cup whole wheat flour
1/2 cup light parm. cheese
water(whatever feels right)
Mix together and press into a crust. Cook for 15min @ 350 degrees. Cook up some loose lean ground beef or ground turkey. Add whatever sauce you want to the crust, then the meat, then some onion, peppers, shrooms, etc. and some low fat mozz cheese. Cook again for 15min @ 350.
