Cheesburger Soup as seen on Diners, Drive-ins & Dives

I love to watch Diners, Drive-ins & Dives on Food Network so when I saw this soup on the show I had to try it. How could soup taste just like a cheeseburger? I wanted to know. This soup is very nice. The addition of lettuce and tomato really makes it. It was fast and easy to make.
What you need:

1 pound super lean ground beef or ground buffalo
16 ounce can of chicken stock
1 pint half and half
1/2 block of Velveeta cheese, cubed
1 large onion, diced
3 tablespoons butter
2 medium tomatoes, chopped
2 cups Iceberg lettuce, chopped
Salt & pepper to taste
1/4 cup flour mixed with 3/4 cup water

In a large pot, melt butter and onion until translucent, remove. Add ground beef to pot, salt and pepper to taste, and cook till browned and crispy, remove to a plate lined with paper towles.

To the same pot, add your chicken stock and flour slurry, bring to a boil scrapping the meat bits off the bottom. Add half and half and Velveeta and cook till the cheese is melted, not boiling. Add the onion and meat to cheese mixture. Season to taste and lower heat. Cover and cook for 10 to 15 minutes, stirring frequently.

You can add the lettuce and tomato to the pot of soup or garnish each bowl.

*NOTE: The recipe I printed from the internet said to cover and cook for 1 hour. I cannot imagine cooking a soup with half and half for one hour without it ruining. Mine turned out just fine cooking it for less time. I used 2% Velveeta instead of the regular. I also didn't use half the block, but about an inch less than half.
