Vegetable Beef Soup my Daughter Loved

This isn't in my diet but I made it for family and my daughter wanted the recipe.

Cut up some potatoes with the skin on, and carrots. Purée a can of tomatoes in the blender. Put that in crock pot on high with some water, boullion, seasonings for about two hours (it gives the vegs a head start). While that's in crock pot, brown a pound of hamburger with an onion and add it to the soup after it's been cooking for two hours. Then turn to low and let cook for several more hours. If you don't have a lot of time, just do this in a pot on the stove. I used chicken flavor "better than boullion". I think cooking it for hours mellows out the tomatoey taste.
