For a richer flavor, consider using vegetable broth instead of water. If you don't have fresh parsley, dried parsley can be substituted, but use half the amount. Adjust the amount of cayenne pepper to control the level of heat. A dash of your favorite hot sauce can also be added at the end. For a smoky flavor, add a teaspoon of smoked paprika to the pot with the other spices. To make this dish ahead of time, prepare as directed, let cool completely, and store in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave before serving.
