Keep food choices local to cut down on packaging and transportation emissions from shipping long distances. Check out local farmers markets for great tasting, fresh seasonal fruits and veggies that you can turn into appetizers, soups and more. This helps support the local farming community and local economy as well.
Keep it waste free by using reusable plates, napkins, silverware and cups. Stay away from the idea that everything including paper goods need to be football themed to make it a great party. This will help keep disposables ending up in the landfill.
Encourage guests to bring reusable food containers so they can bring home leftovers, or lend them some of your containers.
Try to avoid serving beverages that come in cans. If you do serve beverages in cans, clearly mark an area that guests can put their empties for recycling. Look for nearby breweries and wineries to keep it local and consider making a pitcher or two of sangria.
When you head out shopping for your party, remember your reusable shopping bags and plan your trips to avoid wasting gas.
