Use modern amenities, but try to keep them hidden when not in use.
Get rid of as much trash as you can before you go.
Ways of doing this are :
- cracking open eggs into a jar and discarding the shells, at home, before you leave. When you get to the event you can simply pour the eggs that you need, right out of the jar.
- recycling the box from dry food stuffs and putting the contents, along with the cooking directions, into a reusable container.
- pre-cooking Deviled Eggs: Hard boil eggs. Place whites in a reuseable container and the egg yolk mash into a reusable icing cone (the type bakers use). At the event, pipe the mash directly into the whites just before serving.
- pre-cooking pasta and putting into a reusable cntainer. Pour hot sauces on the pasta, on site, and serve. The heat from the sauces is generally hot enough to heat the entire dish.
- peeling and cutting cantaloupe and other melons, at home, and place in into a reusable container.
Bring as many "no-cook" foods as you can.
Nobody wants to slave in the kitchen either cooking or cleaning up when they could be enjoying some other activity!
Some examples of no-cook foods:
- Bread and cheese
- Fruit, fresh or canned
- Cold cooked meat (aka: cold cuts)
- Raw vegetables (sliced, pared etc.) maybe with a dip
- Deli or take out food (stews, chickens etc.)
- Salads (green, macaroni or potato)
- Hard boiled eggs
- Pickles, olives, antipasto
- Cakes, cookies, other baked goods, etc.
