1. Combine the horsemeat, feta, onion and parsley in a bowl. Season to taste.
2. Make four hamburger patties. Barbecue on medium heat for 8 to 10 minutes or until the internal temperature reaches 70˚C (160˚F). Turn over half-way through the cooking time.
3. While the hamburgers are cooking, toast the buns. Place each ham-burger on a bun. Garnish with lettuce, tomatoes, tzatziki, and black olives.
