Pour a little more than half of the water into a saucepan. When the water boils, throw all the other vegetables. I cut them. In general, you can put any leftover vegetables in this broth, the French (especially cooks) put both trimmings and skins.
When you put all the vegetables in the broth, fill the pan with water so that it is full, and again it is necessary to bring the broth to a boil. When it boils, add the bay leaf, peppercorns and green stalks. I always buy greens, pluck them from the stems, chop them finely and freeze them. And the stems are also wrapped in foil and frozen until a trace appears. we prepare the broth.
