Ah I might be confused by my low english skills but it seems grains and legumes are vegetable. I was curious and a quick search returned several sources confirming that however I'd be pleased to learn other usages.

> a plant or part of a plant that is eaten as food. Potatoes, beans and onions are all vegetables.

I'm don't want to argue on definitions though but the chicken/tomatoes comparaison hardly make sense in an answer to satvikpendem: he mentioned vegatable in comparaison to meat in a poor people diet. In that situation one would certainly aim mainly for cheap and nutritious staples AKA grains and legumes instead of tomatoes.

At least we agree on the regulation impact! I wish you a pleasant Californian day :-)
