I prefer using a stock pot to make this soup.  It is the quickest method, although a little more hands-on. However, you can also use an electric pressure cooker, such as an instant pot or Fagor multi-cooker. Instructions for electric pressure cooker: Cook the hamburger on the brown setting.  Add the rest of the ingredients. Secure the lid and pressure cook on high for 15 minutes.  Release the pressure manually, or let it release naturally. You can also use a slow cooker.   Instructions for slow cooker: Brown the hamburger in a skillet.  Add the ground beef and the remaining ingredients to a slow cooker. Cook on low 4 to 5 hours (or high 2 to 3 hours), or until vegetables are soft.
