Most of us have tried the free food samples at our local supermarket. They are usually chips, dips, sausages, cheese, or similar "finger food." While not always delicious, it is usually much better than a tiny bag of pretzels or peanuts that we get on a short airline flight.
Why not make the food samples available to airline passengers. It would be a step up from what we get and wouldn't cost the airlines. Passengers could also fill out an optional opinion form and perhaps get a coupon to purchase the item.
