There is a killer BBQ/Smokehouse restaurant that is out in the middle of absolute nowhere. As in the "city" they are in is located in a county with a Census measured population of 4000 people. We drive 40 minutes to hit this place at the opening at least once a month because of how they deal with waste food.

Burgoo

All the waste meat, veggies, stock etc is throw into a massive cast iron pot and put in the "cool" side of the smoker over night. When they open in the AM, the burgoo is ready, and it is amazing. Every day it is different, every time there will be a different wave of flavors. We had it one month where they had a ton of left over chicken, with just enough smoked pork and beef ribs to make the flavors mix. The burgoo is available at the open for $6 a bowl, and it is GONE within two hours of open. Looking at the pots they use, they must make close to 40-50 gallons. The place gets packed, standing room only, I bet the whole town shows up some days.

The place never trows away meat, and uses all the veggie 'waste' for stock. The only thing they throw away is packaging.
