I prepared the filling with: chopped garlic, onion & chive cream cheese, grated parmesean cheese, shredded cheddar, bacon bits, mexican cheese, a shake of Old Bay Blackened, some Tobasco Chipotle to taste, and a good dose of horseradish sauce. About half of everything (except chorizo) goes into the bowl to be mixed. This will work for about 50 oysters (1 case). Once mixed, just spoon it over the opened oysters. Make sure they are washed and dried after opening.
