Cheeseburger Or Hamburger Soup with Dairy Free Option

I can certainly not take credit for this recipe.  This is my very slight adaption of Kelly Broyzna's Dairy-Free Cheeseburger Soup from the The Spunky Coconut.  Do check our her many delicious recipes.
I have made this recipe about five times since I first discovered it in December.  It is so delicious and a definite family favorite. The added cheese is not needed, but I will admit I have a little weakness for cheese in my tomato soup.  This recipe is easy to make and very filling.  With a lot of lettuce and cilantro on top it definitely eats like a complete meal.
I normally add a lot more lettuce on top of my soup  but didn't want it to take away from the soup.
