Yeah Taskmaster (which I adore) came to my mind too. I think it's more common when the food in question is an animal product, but still it just seems a bit contrived when behind the scenes the catering company is probably chucking tons of food the talent didn't feel like eating on a given day anyway.

It's entertainment, it has an environmental cost, sometimes a big cost. I don't think you need to signal that it's unacceptable for that cost to be paid solely for entertainment's sake. What's the difference between some food waste and burning fuel to drive a boulder out of town for a laugh.
