Preheat oven to 400°F and cover a baking sheet with parchment paper
Add all the meatball ingredients (except for the green onion garnish) to a bowl and mix until combined
Roll the meatball mixture into 2" balls. Place meatballs on the sheet pan. Bake for 20 – 25 minutes or until they are thoroughly cooked
In a saucepan on the stovetop, add all of the sauce ingredients (except for the arrowroot/water mixture) and heat on medium-high. Once the mixture is hot and bubbly, mix in the arrowroot powder dissolved in water. Stir frequently. As the sauce heats, it will begin to thicken.
Transfer the cooked meatballs to the thickened sauce and thoroughly coat the meatballs
Serve over cauliflower rice and garnish with green onions and sesame seeds, enjoy!
