Preheat the oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease it.
In a large bowl, combine ground chicken, grated zucchini, grated carrot, green onion, and spinach.
1 lb ground chicken, ½ cup zucchini, ½ cup carrot, ¼ cup green onion, ¼ cup spinach
Add egg, garlic powder, onion powder, smoked paprika, salt, and black pepper. Mix well until everything is evenly incorporated.
1 egg, 1 tsp garlic powder, ½ tsp onion powder, ½ tsp smoked paprika, ½ tsp salt, ¼ tsp pepper
Scoop out about 1.5 tbsp of the mixture and roll into small balls or flatten slightly for patties. Place them on the prepared baking sheet, spacing them slightly apart.
Bake for 18-22 minutes, flipping halfway, until golden brown and cooked through (165°F internal temperature).
Enjoy warm with a dip like Greek yogurt ranch, hummus, or tahini sauce. Store leftovers in the fridge for up to 4 days or freeze for later.
