You phone the salad rental depot nearest you and they pop round with a lovely bowl of salad for your party. The guests see the healthy vegetables and rainbow of pretty colours sitting among your tasty beige buffet and judge you to be a good and worthwhile person. Then after the party has finished the salad rental van comes back and packs up the uneaten salad so it can be taken to the next party.
Could maybe rent out pineapples as well for when you have visitors.
Any investors?
