You might pick up a first course like soup from the market, a side dish from a gourmet shop, or dessert from a French patisserie.
Some hosts hire a caterer to make a few dishes, then do the rest themselves.
Others are turning to restaurants. Even if it's not set up for catering, a restaurant will often oblige. The key is to make it relaxed and homey, from the food to the table settings. If you decide to use a caterer, the staff can cook in your kitchen and use your platters, casseroles, and even recipes, for that homemade look. Even when the rest of the meal is bought or catered, hosts like to add a few homemade touches.
