Preheat oven to 500 degrees.
Combine milk and pita in a stand mixer bowl; let stand until bread is soft, about 5 minutes.
Add parsley, mint, oregano, garlic, salt and pepper. Beat until well mixed and pita bread is evenly dispersed in the mixture.
Add ground lamb and mix well until evenly combined.
Form mixture into 1-inch meatballs and place in an oven-safe baking dish. If mixture is too hard to handle, refrigerate briefly.
Place meatballs in the oven on the top rack and brown, turning meatballs as necessary.
