Veggie soup with beef and potato

I must warn you now this makes ALOT of soup.. Great for get together's. I made it last night for 5 people and I have a bunch left over. But the good news is, it freezes great. You can do any combo of veggies you like. This is the way I made it. My husband had about 3 bowls worth.. I served it with toasted sour dough bread. It was a great complement to the soup.
