Triple Slow Cooker Entertaining, by Kathy Moore and Roxanne Wyss, contains 100 recipes and 30 party plans for your slow cooker. Although the authors have triple slow cookers in mind, the recipes are for use in one crockpot. So, no adapting needed.

This cookbook has parties in mind, but I think the cookbook is good for any dinner, with much variety of delicious, hot, slow-cooked food!
Party plans from New Year's Eve to Adult Birthday Parties to Pasta Parties are at the beginning.
Then the cookbook starts with recipes for Dips and Cheese Fondues, Appetizers and Snacks, Soups, Chilis and Sauces, Main Dishes, Sides and Salads, then Sweet Endings and Hot Drinks.
