If needed, soften the dates by soaking in hot water for 10 minutes. Pit the dates and add to a food processor and blend until finely chopped. Set aside.
Steam the sweet potato by adding it to a bowl along with about 2 tbsp of water. Cover and microwave for 4-5 minutes to soften. Alternatively, you can steam in a small pot by adding 3-4 tbsp of water, bringing to a low simmer, and covering for 5 minutes until soft. Squeeze with a towel to strain excess liquid. Allow to cool to the touch.
Combine the sweet potato, dates, turkey, seasonings and fold until well combined.
Form the mixture into 7-8 sausages that are round and slightly flattened. Set aside.
Using a large deep pan, heat the avocado oil over medium-high heat. Add 2-3 sausages to the pan at a time, being careful to not overcrowd the pan. Cook for 3-5 minutes on each side or until crisped and browned. The internal temperature should read 165 F.
