Apparently Oprah is going vegan for three weeks as part of a "cleanse". is doing a special series for her audience who are trying it with her: a podcast a day for 21 days. Tip for Oprah, or anyone else contemplating The Big Switch: from your first day menu, you aren't getting enough protein. Keep it up and by the end of the week you'll think you're missing eggs, when all you need is a good tofu scramble. It's really not hard to toss some cubed tofu on a salad or add some seitan curry to the menu. And Alessi makes a really quite delicious vegan split pea soup mix.
