Answer:
High fat reward for making it through another solar cycle
I'm a flat circular spongy roll made from yeast dough and eaten toasted and buttered
As soft as silk, as white as milk, as bitter as gall, a thick green wall, and a green coat covers me all.
Before crust hardens.
When do you start when it’s red but stop when it’s green?
By Moon or by Sun, I shall be found. Yet I am undone, if there's no light around
