Preheat your oven to 400°F (200°C).
In a large bowl, combine the ground lamb, breadcrumbs, egg, garlic, onion, parsley, cumin, paprika, salt, and pepper. Mix thoroughly until well combined.
Shape the mixture into 1-inch (2.5cm) meatballs and place them on a baking sheet lined with parchment paper.
Drizzle the meatballs with olive oil and bake for 20-25 minutes, or until they are browned and cooked through.
While the meatballs are baking, prepare the tzatziki. Squeeze the grated cucumber to remove excess moisture.
In a bowl, combine the Greek yogurt, squeezed cucumber, lemon juice, dill, garlic, and salt. Stir until well blended and refrigerate until ready to serve.
In a small saucepan over medium heat, combine the pomegranate juice, honey, and balsamic vinegar.
Simmer the mixture until it thickens and reduces by half, about 10-15 minutes. Remove from heat and let it cool.
Place the lamb meatballs on a plate, drizzle with the pomegranate glaze, and serve with a side of tzatziki sauce.
