Once you know what it is and how it's used, it would be hard for anyone who eats sausages or (most) hot dogs to object all that much.

Taken alone, the processed product bears a pretty close similarity to most canned cat/dog food, some of which is arguably a "more healthy" diet than many humans consume.

As to pizza being a vegetable, the USDA says only that the vegetables in/on a pizza (they must mean the olives???) can be counted as part of the "vegetable quota" each meal should contain. That pizza is a vegetable misstates what the feds said.

The effective standards only specify a "balanced total nutritional content" for each complete meal served (or at least made available) for each person, and the individual components that make it up are pretty vaguely defined and subject to interpretation by the cook.
