In a large bowl, thoroughly combine first 4 ingredients (beef through coconut flour); form mixture into meatballs.
Prepare sauce: In a medium bowl, combine next 7 ingredients (honey through arrowroot powder); set aside.
Melt the coconut oil in a large skillet with a tight-fitting lid over medium heat until hot. Add meatballs; cook for 5 minutes per side or until browned then pour sauce over the top. Reduce skillet heat to low, cover and simmer for 10 to 15 minutes or until meatballs are cooked through and sauce has thickened.
