Baked Potato Bar? Sounds yummy. With all that you have going with the baked potatoes and desserts, I'd keep the salad super simple like your favorite bag of greens. Splurge on a choice of dressings to satisfy all your guests. Or if you want to keep it all homemade, I'd try Mixed Baby Greens with Balsamic Vinaigrette or Mixed Green Salad with Dijon Vinaigrette. What a great host you'll be!
