Adapted from the Six-Ingredient Solution cookbook, this is a simple recipe that requires some time, but not much effort. Do not skip the Boursin cheese because it adds a lot of flavor. If you want a dairy free tomato soup, Cook's Illustrated has a recipe for Creamless Creamy Tomato soup that I recommend.
If you are not sure what to do with the other half of the Boursin, make a double recipe and freeze the leftovers. I've found the leftovers to be just as delicious as when fresh. The original recipe called for brown sugar instead of white, but I found it a pain to sprinkle over the tomatoes, so I use white instead. There is a tiny bit of extra flavor in the brown, so you can use that if you prefer.
