Every week, we invite you to participate in the HealthyYum community by using a particular food or ingredient picked by one of our users, posting it on your blog and uploading the picture to HealthyYum.com.

The challenge for the week of Nov. 23-29 is sponsored by the letter "R" for RED! I know it sounds weird, but red usually means healthy antioxidants, so bring on recipes with cranberries, beets, red peppers, tomatoes, and any other healthy foods you can think of that's red. (Submit your photos by Sat. Nov. 30, 2009, 11:59 PM EST for a chance to win).

Need inspiration, check out this Insalata Caprese - Diced Caprese with Basil Pesto by somaR and Slow Roasted Tomato Soup by twopeasandtheirpod.

As usual, the details are in our weekly newsletter, so sign up already!
