Ground beef and a package of frozen vegetables are your two main shopping list items for this quick-to-make soup. A hearty stock is provided by tomato sauce, dry onion soup mix, and a teaspoon of white sugar.
Using a pressure cooker to make this flavorful chicken soup speeds time cooking the pearl barley; a process that normally takes 1-2 hours can happen in 9 minutes. If you don't have a pressure cooker, use a heavy stockpot for stovetop cooking, add more stock, as some will cook away, and allow more cooking time.
This savory Italian-inspired soup is full of cannellini beans, fresh Swiss chard, and tiny pasta. A piece of Parmesan cheese rind builds a deep base of flavor — but use grated Parmesan if you don't have one.
