For our money the best and easiest to use prepared pasta is Tinkyada's.  The lasagne noodles are

excellent.  If you're willing to make your own pasta, don't be shy about trying Bette Hagman's recipes from her Gluten Free Gourmet cookbooks.  Also, experiment with substituting low fat cottage cheese for ricotta for a cheesier, more sturdy, layer.  

Chow for now!
