I saw Viva Daisy too! She's originally from the PBS channel, and I have one of her cookbooks. I remember her being thinner and having shorter hair. She cooks really down home latin foods. You really have to check her out. She's great. You might want to look for her old PBS shows too, Daisy Cooks. I'm worried they're going to try to "food network" her show and make her less of what I liked watching. They already have her hair different, although maybe she decided that herself.

Here's her cookbook, which I have.
