In a large bowl, mix together chicken, zucchini, green onion, cilantro, garlic, salt, pepper, and cumin (if using). Mixture will be quite wet.
Scoop into meatballs with a small scoop or heaped tablespoon and gently smooth with your hands. I can usually get around 20-24 poppers. You may be able to get more or less, depending on how large you size them.
To cook on the stovetop:
Heat a drizzle of oil in a medium pan over medium-low heat. Cook 4-5 at a time for about 5-6 minutes on the first side.
Flip and cook an additional 4-5 minutes, or until golden brown and the centers are cooked through.Serve with guacamole, salsa, or your favorite dip.
