I struggled with this very issue for a few years before I "figured it out!!!"
I love Cookinglight.com for lighter versions of originally, fattening recipes. It's so easy! Visit the website, you can search dishes by a certain ingredient, a category (aka appetizers)...etc...
I love the books by Bill Phillips, "The Body for Life" and the newest, "Eating for Life." Tons of great variety, that taste and look great for all times!
Two other strong sources for me include, but are not limited to: Oxygen Magazine and Muscle and Fitness Magazine. Each month brings new flavors and trends into fitness foods. I'm sure there are many other people out there who have their own scrap-book cook books, with millions of cut-out magazine pages like me... :P
No matter what you choose to use as your source(s) for healthy and fun recipes...some of your friends will regect your food because it IS healthy. Some people just suck when it comes to eating clean! I always choose a recipe I know I can enjoy. At least I have a food that I may eat while I'm at the event. Usually I have a gigantic cooler that is attached to my hip with meals prepared to eat... LOL...My friends hate me when I come over with my cooler...
I hope you find that information useful!
