Preheat the oven to 375 degrees. In a large mixing bowl combine the ground turkey, chopped spinach, feta, breadcrumbs, egg, onion, garlic, oregano, salt, and pepper until evenly mixed.
Divide the mixture into four equal portions and shape each into a small loaf. Place the loaves on a rimmed baking sheet with space between them.
In the same bowl toss the potato wedges with the olive oil, lemon zest, lemon juice, salt, and pepper until coated. Arrange the potatoes around the meatloaves on the baking sheet.
Bake for 30 to 35 minutes until the internal temperature of the meatloaves reaches 165 degrees and the potatoes are golden and tender. Let the pan rest for five minutes before serving.
