Vegetable imagery

Lovely photo, yes? A photo by Gloria-Leigh Logan, at Acclaim Images Stock Photography.

Can you identify all the vegetables? I count at least 15, more if you count each color of sweet pepper separately.

However, there is a piece of something that does not look to me like a vegetable, but a fruit.

There will be a prize for the person who IDs the most vegetables correctly and makes the best case for the fruit being a vegetable, or vice versa.
