Preheat oven to 400 degrees. Line a sheet pan with parchment paper or aluminum foil. If using foil, grease with oil to prevent sticking.
Add turkey to a large bowl. Place grated carrot and zucchini in a kitchen towel and squeeze to remove any excess liquid. Add dry veggies to the bowl. Add spinach, garlic powder, sesame oil, egg, and almond flour/breadcrumbs.
In a small bowl, mix tamari/coconut aminos and honey until honey is dissolved (not at the bottom of the bowl). Add 2 tablespoons of the sauce to the bowl with the other ingredients. Mix very well with a large spoon or rubber spatula.
Once the meatball mixture is well combined, use a 2 tablespoon cookie scoop or your hands to portion into 24 meatballs. If using your hands, keep them wet (rinse under water) to prevent the meat mixture from getting too sticky.
Spoon a little more of the sauce mixutre of each meatball before baking. Bake until cooked through and lighly browned, about 12 minutes. Sprinkle with sesame seeds, if desired. Serve warm with rice or noodles.
