Knowing how to make tomato soup is one of those skills every home cook should have -- canned tomato soup don't hold a candle to the flavor and texture of homemade, and it's ridiculously simple to make. The reason this recipe is extra easy is because it uses canned tomatoes, so there's no fretting over what type of tomato to use, or whether the tomatoes are at peak ripeness (in fact, canned tomatoes often have better flavor than what you'll find in the produce section during much of the year).
