We like a muffin called "Our Daily Muffin" distributed by a company called
American Marketplace Foods.  Each muffin has 50% of RDA calcium, and 60%
vitamin A.  Plus they're fat free and have 9g of fat per muffin.  They're
advertised as dairy and yeast free, as well as 100% vegetarian.  

We find the muffins at the local health food store and a local supermarket
chain.  For product info, you can call 1-800-muffin-4u, or visit their web
site at www.ourdailymuffin.com
