Heat the oven to 450F. In a medium saute pan or skillet, heat 1 tablespoon olive oil and cook the andouille until brown. Add the remaining tablespoon of oil and the butter. Saute the green onions, garlic and parsley until tender, about 3 to 4 minutes. Add the diced artichokes and lemon juice. If the dressing seems dry, add some wine, stock or water liquor to moisten. Saute for about 2 minutes. Remove from heat, add the bread crumbs and the cheese and toss lightly.
 
Place 2-3 shrimp in each ramekin. Top with the artichoke dressing. Bake until browned, 10-15 minutes. Serve with a drizzle of Hollandaise sauce over the dressing.
 
Note: You may replace the shrimp with oysters and adjust the cooking time for 10-15 mins.
