Preheat oven to 400. Bake pie shells 10 minutes with pie weights, then another 3 minutes without pie weights. Beat eggs. Whisk nonfat dry milk into lowfat milk with wire whisk and add to eggs. Add ham, mustard powder, cheeses, wine, basil, salt, and pepper. Divide and pour into two pie shells, making sure you evenly distribute the ham (and mushrooms if you're using mushrooms) and bake for 30-45 minutes or until knife inserted into the center comes out clean. Using the convection setting on your oven shaves about 10 minutes off the time.
