Make three foil packets using about 2' by 2' of foil. Fill each with 12 clams, 1/3 tsp salt, pepper, drizzle of olive oil, 1/3 of the sausage, onion and red pepper. Mix the 2 oz. of white wine with the garlic paste and add to each package. Top with a dab of butter.
Fold the foil up tightly to form a packet. Heat the BBQ to medium (375F) and put the packages on the grill. Close the lid and cook for 10-12 min. Shake each pouch gently after 7 min. and continue to cook. Alternatively cook on an open fire grill, shaking gently every few minutes.
Open up packages and garnish with parsley. Serve immediately with crusty bread or buns for dipping.
