Combine all ingredients in a mixing bowl. If mixture is to wet add more almond flour. Form meatballs into golf ball size and lay on parchment. Cook for 15 minutes.
If using an air fryer preheat to 400 and cook for 8-10 minutes, until temperature is 165 degrees.
Teriyaki Sauce
Combine all ingredients except arrow root powder to a sauce pan. Bring to a boil, reduce to med-high. Make a slurry by removing some contents from the sauce pan into a small bowl. Sprinkle in arrowroot to the small bowl while whisking. Once combined, take the small bowl and pour it slowly back into your sauce pan, whisking the entire time. Once it heats up some it should thicken and become glossy. You know its the right consistency when it sticks to the back of the spoon.
