For the tiny meatballs:

• 1/2 lb ground pork
• 1/2 lb ground extra lean beef

• 1 tablespoon of freshly chopped parsley
• 3 tablespoons of breadcrumbs
• 1 tbsp of milk
• 1 egg

For the soup:

• 3/4 cup of acini de pepe pasta East Side Mario's uses this, but you can substitute any other small pasta if unavailable

• 1/4 tsp lemon zest optional
• 7 cups of chicken broth if using store-bought, 2 cartons of around 900ml each
• 1/2 teaspoon of garlic powder
