Most of the vegetable matter in my compost bin is peelings. Tough peelings like bananas and avocados I cut into small pieces. I do the same with fruit rinds. Since I do not tend to my compost bins as well as I should I try to avoid putting seeds, pits or potato eyes in the bins. Even with that caution I occasionally get volunteer plants in the bins. When I get volunteers I usually just pull them out, cut off the roots, chop them into smaller pieces then return them to the bin.
One year we had a volunteer watermelon. G got excited about the vine and insisted that I let it grow. It grew, and grew and grew. It finally produced 3 small melons. I harvested them when the stem dried up. They were flavorless. Not worth the space that they occupied.
My 2 cents.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant. ~Author Unknown
