Preheat oven to 400′ F. Line baking sheet with parchment paper. You can also place a wire rack on top of baking sheet.
Place the steamed broccoli, carrots, spinach and parsley in a food processor and blend until broken down into fine pieces.
Add the blended vegetables to a large bowl along with the ground turkey, egg, olive oil, breadcrumbs, garlic powder, salt (if using) and pepper. Combine all meatball ingredients until well incorporated.
Roll turkey veggie mixture into about 26-28 small meatballs (you can use a small cookie scoop to form uniform balls) and place onto prepared baking sheet.
Bake for 15-18 minutes, until baked through and slightly golden. Serve warm with your favorite sauce or sides.
