Notes

For even more flavor, feel free to add extra herbs and seasonings that you enjoy. For instance, try 2 teaspoons of Italian seasoning, 1/2 teaspoon garlic powder, and 1/4 teaspoon onion powder. You might like a pinch of red pepper flakes for heat. You can also replace 1 cup of the water with red wine, or substitute low-sodium beef broth for all of the water.
