You can also give everybody the chance to bring a dish of their choice. Let’s face it –In a time where you're likely to have friends following low-carb, low-fat, and low-calorie diets, it's almost impossible to accommodate everybody. By letting guests bring a dish, you're taking the pressure off you and giving them a way out.
If you're the one organizing the party, you can offer to provide drinks and dessert while guests bring the main dishes. It's a win-win situation.
Remember that a successful party is not so much about the food as it is about enjoying the people there. Happy skinny partying!
