In a bowl, combine ground yak meat, breadcrumbs, eggs, minced garlic, Italian seasoning, salt, and pepper. Mix well until evenly combined.
Form the mixture into meatballs, about the size of a golf ball.
Heat a few tablespoons of olive oil in a skillet over medium heat. Add the meatballs and brown on all sides.
Pour tomato sauce over the browned meatballs, reduce heat to low, cover, and let simmer for about 20-30 minutes, or until meatballs are cooked through.
Serve hot with pasta or bread
