A simple soup doesn't have to mean simple flavors. Case in point, this rich and hearty recipe, which packs turkey sausage and potato gnocchi into every bite. You'll start the sausage with the onion and garlic so that the rendered drippings infuse the broth. Add a can of diced tomatoes, and all that's left is poaching the gnocchi in the liquid as it simmers and folding in a handful of baby spinach. The result is a generous recipe that you can get together in just half an hour.
