Preheat oven to 350 degrees. Place bread in food processor. Cover and process into crumbs.
Combine eggs, bread crumbs, green onions, garlic, thyme, salt, and pepper in a bowl. Add ground turkey; mix well. Shape into 40 meatballs. Arrange meatballs on a large rimmed baking pan. Bake 20 to 25 minutes or until done (165 degrees). Cool slightly.
Combine honey, ketchup, sriracha, apple cider vinegar, and garlic powder in a saucepan. Bring to boiling; reduce heat. Simmer, uncovered, 5 minutes. Brush meatballs with sauce and sprinkle with sesame seeds, if desired. Serve over brown rice.
