Preheat a large skillet or Dutch oven over medium heat. Mix meat with zucchini, garlic, ginger, salt, and pepper.
Roll meat into balls and arrange in hot skillet. Cover and cook for several minutes, then turn. If they don't quite cook through during this stage, that is fine. You will probably need to cook the meatballs in batches, removing the cooked ones to a large bowl, until all the meatballs are done.
Return all the meatballs to the pan. Add the honey, sesame oil, and coconut aminos or soy sauce. Stir to mix. Cover and heat through, then uncover and let them simmer for 15-20 minutes, stirring occasionally, until the sauce has absorbed into the meatballs and the outsides of the meatballs caramelize a bit. Don't let them burn! When the aroma deepens, they are beginning to caramelize. Watch carefully at this point, stirring more frequently.
Remove from heat. Serve plain or with rice or cauliflower rice, and garnish with sesame seeds and/or green onions.
