Just a little chipotle in adobo sauce can go a long way into fueling the fire of your traditional tomato soup. Chipotle pepper adds a delicious smoky heat, and a little extra adobo sauce provides a nice earthy undertone to the soup. For those only moderately into spicy foods, we recommend using only one chipotle, but for those with more adventurous taste buds, you could add a second for some bigger heat. Serve with crusty bread, and you have yourself a delicious and filling spicy lunch
