In a large bowl, mix together all the meatball ingredients. For best results we suggest you use a microplane for the garlic and crumble up the feta well. Cover and let rest in the fridge while you prepare everything else.
Preheat your oven to 400°F (200°C).
Wash and chop your potatoes into 1 inch cubes. Wash the zucchini and cut them in 1/2 inch half moons.
Season the veggies with oil, garlic powder, salt, pepper, and lemon juice.
On a large sheet pan, add the potatoes and bake for 10-15 minutes.
While they bake, remove the meatball mixture from the fridge and form 1 inch balls. Work with wet hands for easy handling.
Remove the sheet pan from the oven and add the meatballs and the zucchini.
Continue baking at 400°F (200°C) for another 10-15 minutes or until the meatballs are cooked through, reaching an internal temperature of 165°F (74°C).
Garnish with feta cheese and fresh chopped herbs.
