In medium mixing bowl, mix together salmon, mashed sweet potato, green onions, coconut oil and salt. Set aside.
In a small bowl, whisk together the tapioca starch and water until the starch dissolves. Add to salmon mixture and mix until incorporated.
Form mixture into 4 patties.
Add coconut oil to frying pan (1/2 - 1 tbsp) and heat over medium heat until oil has melted and pan is hot. Once oil is hot, add the patties. Cook for about 3-4 minutes on each side.
Enjoy!
Notes
*If you do not already have a mashed sweet potato on hand, you can quickly cook one in the microwave. First prick the potato a few times, then bake in microwave for approximately 4 minutes until tender and able to mash.
