Easy Creamy Tomato Soup

Needed a really quick dish for supper so I opened two cans of Trader Joe's whole tomatoes with basil and wizzed them up with the immersion blender. NOTE: Do not lift the blender up while blending - very messy. In the meantime I carmelized 1/4 of a red onion. After the onion was done I added it to the tomatoes along with some coarse salt, pepper, and garlic salt. I let the soup simmer for about 20 minutes or so. Added some heavy cream at the end and cooked just until cream was heated. Added some dice blue cheese just before serving - yummy. A perfect fall soup. Would be delicious with toasted croutons on top.
