Also known as gnudi, these italian-style ricotta dumplings are little pillows of dough that have a supple texture once cooked. They are often boiled in a pot of salted water, similar to gnocchi, but here they are simmered in the same seasoned tomato sauce they'll be served with. When mixing the dough for the dumplings, add just enough breadcrumbs to bind the ingredients; how much you need will depend on the moisture level of the ricotta.
