Place the cooked chicken, cottage cheese, coconut milk, egg, cocoa powder, sweetener, LMNT and vanilla into a food processor or blender and puree until very very smooth. Taste and adjust sweetness to your liking.
Place the mixture into a Ninja Creami container. Cover and place in the freezer for at least 7 hours or overnight.
When ready to consume, allow to sit on the counter for 10 minutes (or sit in hot water for 1 minute). Making sure it doesn't get too liquidy yet soft.
Place in the Ninja Creami on the “lite” setting. This will spin for about 3 minutes. Check consistency and if you desire a creamier texture, run the mixture on the “gelato” setting. Depending on your desired texture, will determine your settings. Enjoy!
