In a large wok or pan, cook sweet potatoes over medium-high heat. Do not use oil as it will make them mushy. Stir often. They are done when slightly soft - about 15 minutes.
Meanwhile, in a large pot, combine Brussels, sprouts, peppers, carrots, celery, onion, ginger, coconut oil, water and cumin. Cook over medium heat, stirring often for about 15 minutes.
Lastly, in a medium pan, brown ground sausage. Set aside.
When everything is done cooking, combine EVERYTHING into the wok with the sweet potatoes.
