Tear herbs and greens from stems and rinse. Dry in salad spinner.
In food processor, combine garlic and shallots, herbs, and greens with one and a half sticks of butter, cubed. Pulse a few times then add Pernod, Tabasco and kosher salt and coarse cracked pepper to taste. Pulse again until mixture is finely chopped.
Melt 1/2 stick of butter, add to panko crumbs and parmesean cheese.
Place rock salt in bottom of cooking tray and arrange oysters on the half shell by nestling them into the salt.
Scoop a generous portion of the greens mixture on top of the oyster. Top with a sprinkling of the panko/cheese mixture. With a fine zester, grate additional Parmesean on top.
Broil for 6 to 8 minutes until golden. Serve with lemon wedges.
Note: If you have extra green/herb mixture, you can create a "non-oyster rockefeller" by nestling a scoop of the mixture directly on the rock salt and scooping it onto a crostini after baking. It makes a nice "chef's treat!"
