Shred your sweet potato. You can do this by hand, but I prefer to use my food processors shredding attachment - this saves me oodles of time (this inexpensive food processor has been a workhorse and served us well for over 5 years now).
Cook your ground sausage in a skillet then set it aside.
Melt the coconut oil in a large skillet. Fry the shredded sweet potato in the coconut oil. Let it brown on one side, then flip it.
Once the sweet potatoes have been browned and cooked through, add the cooked sausage, cinnamon, and salt. Toss it all together.
