Preheat oven to 400°F (200°C).
In a mixing bowl, combine ground turkey, breadcrumbs (or almond flour), chopped onion, minced garlic, egg, salt, and pepper. Mix until well combined.
Shape the mixture into meatballs about the size of golf balls and place them on a lined baking sheet.
Bake in the preheated oven for approximately 15 minutes. For extra crispness, broil for an additional 2-3 minutes until golden brown.
While meatballs bake, prepare rice or couscous according to package instructions and chop cucumbers.
Assemble your bowl by starting with a base of rice or couscous, topping with meatballs, chopped cucumbers, olives, and generous spoonfuls of tzatziki sauce.
Garnish with fresh dill and lemon wedges before serving.
