Earth Balance spread (like margarine) is very edible. It melts well and is flavorful. Daiya cheeses too. Vegenaise actually tastes better than mayonaise. Of course, all of these are processed foods, and while I don't think they're harmful, niether are they especially nutritious. But for flavor, and helping to transition, they're pretty good. I've used them for years, and my overall health has steadily improved, from when I was eating the "real" stuff.
