I would have a much better shot at being a vegan if I could make a good cream sauce (like for pasta or scalloped potatoes). Is there one you recommend?

I have several creamy pasta sauces in both of my cookbooks, such as the Broccoli Pesto Pasta (p. 160, HHC ) and the Sun-Dried Tomato Cream Sauce (pg. 208, EHH ), as well as the one on the blog, Instant Vegan Alfredo . I don't have a recipe for scalloped potatoes, but I've seen tons of recipes online and in vegan cookbooks.
