porketta recipe

Does anyone have an authentic recipe for Porketta?  All my online searches seem to yield the same two recipes (posted below). Any input would be of great value.  I will probably take the best of both recipes and combine, unless anyone can point me in the right direction.

most common recipe found all over the web:

• 2 pound boneless pork loin roast
• 3 tablespoons dill seed
• 1 tablespoon fennel seed
• 1/2 teaspoon oregano
• 1 teaspoon lemon pepper
• 1/4 teaspoon onion powder
• 1/4 teaspoon garlic powder

and this recipe which I think was from food network

• 12 cloves garlic, chopped
• 1 cup chopped fresh parsley
• 1/2 cup fennel seeds
