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 Sept. 14-20 chosen by healthydelicious is all about LUNCH! This is the meal where things often go awry when we're trying to eat more healthfully. So show us some healthy lunch time options! If you think your recipe is a great lunch idea, then just let us know in the description when you submit the photo.

The winner of this week's challenge will receive a copy of the Flat Belly Diet Cookbook written by editors of Prevention magazine, Liz Vaccariello and Cynthia Sass. All of the recipes were carefully developed to make sure every meal includes just the right amount of monounsaturated fatty acids (MUFAs) and meets the plan's 400-calorie guideline, so readers can mix and match meals to suit their taste.

Okay - forget the title :-) What I love most about the cookbook is that the recipes are simple and easy to make or customize. (Submit your photos by 11:59 PM EST on Saturday September 19, 2009 for a chance to win).

I wouldn't mind having some Rice Paper Rolls like GuiltyKitchen with Bleu Cheese Salad, Falafel Croutons from ghweiss for my lunch this week.

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